Migrate the driver for the v6-based MSM chips into drivers/gpio. The
driver is unchanged, only moved.

No need to have a separate header file containing only register
definitions that are used by a single driver. Fold these into the
gpio driver.

The gpiomux.h header contains some SOC ifdefs. However, the API that
is actually used by the GPIO driver only uses two functions that are
general. Move these general definitions into a public header file.

Select the GPIO register configuration at runtime rather than through
idefs.

Put an SOC prefix on each GPIO register definition, eliminating the
need to have SOC ifdefs around the definitions.

The MSM7x25 and MSM7x27 devices are not yet supported in the kernel.
Remove #ifdef-based tables supporting these chips for now.

Add gpiomux get and put calls to msmgpio request and free,
in order to allow gpio lines to be properly reference-counted
and power-managed.

Install a gpiolib driver supporting the on-chip gpios for
single-core MSMs in the 7x00 family, including 7x00A, 7x25, 7x27,
7x30, 8x50, and 8x50a.
As part of the ongoing effort to converge on a common code base,
this driver is based on the Google-Android msmgpio driver, whose
authors include Brian Swetland and Arve Hjønnevåg.

GPIO support for Qualcomm SOCs requires interaction with the
radio (baseband processor). This API allows the different boards
to enable GPIO through the radio processor in a generic way.
