Paul Walmsley 72e06d0872 OMAP2+: powerdomain: move header file from plat-omap to mach-omap2
The OMAP powerdomain code and data is all OMAP2+-specific.  This seems
unlikely to change any time soon.  Move plat-omap/include/plat/powerdomain.h
to mach-omap2/powerdomain.h.  The primary point of doing this is to remove
the temptation for unrelated upper-layer code to access powerdomain code
and data directly.

As part of this process, remove the references to powerdomain data
from the GPIO "driver" and the OMAP PM no-op layer, both in plat-omap.
Change the DSPBridge code to point to the new location for the
powerdomain headers.  The DSPBridge code should not be including the
powerdomain headers; these should be removed.

* Most OMAP chips have an on-board DSP.
*
* On the 2420, this is a 'C55 DSP called, simply, the DSP. Its
* powerdomain is called the "DSP power domain." On the 2430, the
* on-board DSP is a 'C64 DSP, now called (along with its hardware
* accelerators) the IVA2 or IVA2.1. Its powerdomain is still called
* the "DSP power domain." On the 3430, the DSP is a 'C64 DSP like the
* 2430, also known as the IVA2; but its powerdomain is now called the
* "IVA2 power domain."
*
* The 2420 also has something called the IVA, which is a separate ARM
* core, and has nothing to do with the DSP/IVA2.
*
* Ideally the DSP/IVA2 could just be the same powerdomain, but the PRCM
* address offset is different between the C55 and C64 DSPs.
