The platform code knows the IRQ base, while the irqchip driver
should really not. This is a littly hacky because we still
hardwire the IRQ base to 160 for the combiner in the DT case,
when we should really use -1. Removing that line will cause
a linear IRQ domain to be use, as we should.

We can find out the number of combined IRQs from the device
tree, but in case of ATAGS boot, the driver currently uses
hardcoded values based on the SoC type. We can't do that
in general for a multiplatform kernel, so let's instead pass
this information from platform code directly in case of
ATAGS boot.

For the non-DT case, the mct_init() function requires access
to a couple of platform specific constants, but cannot include
the header files in case we are building for multiplatform.
This changes the interface to the platform so we pass all
the necessary data as arguments to mct_init.

The new common clock drivers for exynos are using compile
time constants and soc_is_exynos* macros to provide backwards
compatibility for pre-DT systems, which is not possible with
multiplatform kernels. This moves all the necessary
information back into platform code and removes the mach/*
header inclusions.

This makes it possible to enable the exynos platform as part of a
multiplatform kernel, in addition to keeping the single-platform
exynos support.
The multiplatform variant has a number of limitations at the moment:
* It only supports DT-enabled machines. This is not a problem in
the long run, as non-DT machines for exynos are going away.
The main problem here is that the gpio code and the exynos_eint
irqchip are not multiplatform capable but still required for
ATAGS based boot.
* The watchdog driver is still missing a conversion.
* sparsemem and memory_holes are currently not supported in
multiplatform.
The the multiplatform aware ARCH_EXYNOS Kconfig symbol is disabled
for now, as dependent patches are still pending in other
subsystem trees. We will enable it once everything comes together.

This patch defines irq numbers of ARM performance monitoring unit for exynos4.
Firs of all, we need to fix IRQ_PMU correctly and to split pmu initialization
of exynos from plat-samsung for easily defining it.
The number of CPU cores and PMU irq numbers are vary according to soc types.
So, we need to identify each soc type using soc_is_xxx function and to define
the pmu irqs dynamically. For example, the exynos4412 has 4 cpu cores and pmus.

A large number of cleanups, all over the platforms. This is dominated
largely by the Samsung platforms (s3c, s5p, exynos) and a few of the
others moving code out of arch/arm into more appropriate subsystems.
The clocksource and irqchip drivers are now abstracted to the point
where platforms that are already cleaned up do not need to even specify
the driver they use, it can all get configured from the device tree
as we do for normal device drivers. The clocksource changes basically
touch every single platform in the process.
We further clean up the use of platform specific header files here,
with the goal of turning more of the platforms over to being
"multiplatform" enabled, which implies that they cannot expose
their headers to architecture independent code any more.
It is expected that no functional changes are part of the cleanup.
The overall reduction in total code lines is mostly the result of
removing broken and obsolete code.

Exynos boot is broken with commit 0529e315 (ARM: use common irqchip_init

to of_irq_init. This does not work because of_irq_init requires interrupt
parents to be in the match list.
Rather than reverting exynos changes, make it do the proper thing by using
IRQCHIP_DECLARE. This requires moving the combiner code to drivers/irqchip.

This contains the bulk of new SoC development for this merge window.
Two new platforms have been added, the sunxi platforms (Allwinner A1x
SoCs) by Maxime Ripard, and a generic Broadcom platform for a new
series of ARMv7 platforms from them, where the hope is that we can
keep the platform code generic enough to have them all share one mach
directory. The new Broadcom platform is contributed by Christian Daudt.
Highbank has grown support for Calxeda's next generation of hardware,
ECX-2000.
clps711x has seen a lot of cleanup from Alexander Shiyan, and he's also
taken on maintainership of the platform.
Beyond this there has been a bunch of work from a number of people on
converting more platforms to IRQ domains, pinctrl conversion, cleanup
and general feature enablement across most of the active platforms.

The recent commit "ARM: EXYNOS: add support for EXYNOS5440 SoC" broke
support for exynos5250 because of_machine_is_compatible() was used too
early in the boot process. It also probably meant that the exynos5440
failed to use the proper iotable. Switch to use
of_flat_dt_is_compatible() in both of these cases.
The failure I was seeing in exynos5250 because of this was:

Commit a5238e360b (spi: s3c64xx: move controller information into driver
data) introduced separate device names for the different subtypes of the
spi controller but forgot to set these in the relevant machines.
To fix this introduce a s3c64xx_spi_setname function and populate all
Samsung arches with the correct names. The function resides in a new
header, as the s3c64xx-spi.h contains driver platform data and should
therefore at some later point move out of the Samsung include dir.
Tested on a s3c2416-based machine.
