The callers of pcf50633_write_block assume pcf50633_write_block return 0 on
success, thus make it return 0 instead of the number of registers written on
success.

Currently pcf50633_write_block is called in drivers/mfd/pcf50633-irq.c and
drivers/rtc/rtc-pcf50633.c.

There are currently four different versions of the AB8500
around: AB8500, AB8505, AB9540 and AB8540. Unfortunately:

- Some of the chips (AB8500, AB8505, AB9540) cannot read
  the AB8500_REV_REG register but return errors

- Some of them have the same ID value in the hardware
  register AB8500_REV_REV, for example the first versions
  of AB8505 and AB9540 have 0xFF in this register -
  just like the AB8500.

So we need to be able to enforce a certain version from
the platform. We do this by using the id of the platform
device that provides the read/write functions.

This patch adds an initial PRCMU register access API, which
for now should only be used for a very limited set of registers.

The idea about this API is that we split the PRCMU driver in
one part that deals with interaction with the PRCMU firmware
and one part that simply provide write accessors in the PRCMU
register range. The latter are just a collection of registers
exposed in the PRCMU register range for various purposes and
not related to the PRCMU firmware.

Currently we support some limited GPIO, SPI and UART settings
through this API.

- We removed the dependency from some domains to the VAPE

  domains are handled outside the framework while ESRAM12
  and ESRAM34 are actually handled inside the PRCMU.

These are the bug fixes that have accumulated since 3.3-rc3 in arm-soc.
The majority of them are regression fixes for stuff that broke during
the merge 3.3 window.

The notable ones are:

* The at91 ata drivers both broke because of an earlier cleanup patch that
  some other patches were based on. Jean-Christophe decided to remove
  the legacy at91_ide driver and fix the new-style at91-pata driver while
  keeping the cleanup patch. I almost rejected the patches for being too
  late and too big but in the end decided to accept them because they
  fix a regression.

* A patch fixing build breakage from the sysdev-to-device conversion
  colliding with other changes touches a number of mach-s3c files.

* b0654037 "ARM: orion: Fix Orion5x GPIO regression from MPP cleanup"
