This adds a scratch pin control interface to the Nomadik pinctrl
driver, and defines the pins and groups in the DB8500 ASIC. We
define GPIO ranges to cover the pins exposed. The DB8500 has
more pins than this but we restrict the driver to the pins that
can be controlled from the combined GPIO and pin control hardware
to begin with.

ChangeLog v1->v2:
- Base on the latest pinctrl development from
  pinctrl-mergebase-20120418 so we can get rid of legacy
  group count mechanism. Also drop the range checks for group
  index, this is handled by the core now.

A recent change to a Kconfig configuration saw MACH_U8500
remove TPS6105X selection. In doing so Kconfig stopped
selecting REGULATORS, which is still required. This patch
sees UX500_SOC_DB8500 explicitly select it instead.

First rename the config option MACH_U8500 to MACH_MOP500
because that is what it's obviously all about, this has
confused me for the last time. Fix some whitespace in the
process.

Since the machine descriptors for HREFv60 and snowball
are clearly in the file board-mop500.c which only
compiles if MACH_MOP500 (former MACH_U8500) is set,
select this for the board variants and nothing else.

For the MOP500 variants the UIB (user interface board)
is probed using I2C so select I2C and I2C_NOMADIK so
we know that this probe will always be successful.

Here we make use of the new System-On-Chip bus driver to export
vital SoC information out to userspace via sysfs. This patch
provides a data structure of strings to populate the base
nodes found in:

/sys/devices/soc[0|1|2|...]/[family|machine|revision|soc_id].

It also adds one more node as requested by ST-Ericsson.

We have decided that this function arbiter fits better in the MFD
subsystem. Since we need to concatenate the split header files we move
it basically like this:

mv mach-ux500/prcmu-db8500.c drivers/mfd/db8500-prcmu.c
mv mach-ux500/include/mach/prcmu-defs.h include/linux/mfd/db8500-prcmu.h
mv mach-ux500/include/mach/prcmu-regs.h drivers/mfd/db8500-prcmu-regs.h
mach-ux500/include/mach/prcmu.h >> include/linux/mfd/db8500-prcmu.h
rm arch/arm/mach-ux500/include/mach/prcmu.h

Then we update different #include statements and Makefile orders etc
to make the PRCMU driver compile, link and boot in the new place
without really changing any code.
