Commit 875a59 (ARM: SAMSUNG: Consolidation of SPI platform devices to
plat-samsung) replaced the function s3c64xx_spi_set_info() with
s3c64xx_spiN_set_platdata() but did not update all the machines, with
Cragganmore being left. Fix that.

This patch introduces common.[ch] which are used only in the
arch/arm/mach-s3c64xx/ directory. The common.c file merges
the cpu.c, irq.c and irq-eint.c which are used commonly on
S3C64XX SoCs and the common.h file replaces with plat/s3c6400.h
and plat/s3c6410.h files.

The S3C64xx SoCs contain a set of gateable power domains which can be
enabled and disabled at runtime in order to save power.  Use the generic
power domain code to implement support for these in software, enabling
runtime control of most domains:

 - ETM (not supported in mainline).
 - Domain G: 3D acceleration (no mainline support).
 - Domain V: MFC (no mainline support).
 - Domain I: JPEG and camera interface (no mainline support).
 - Domain P: 2D acceleration, TV encoder and scaler (no mainline support)
 - Domain S: Security (no mainline support).
 - Domain F: LCD (driver already uses runtime PM), post processing and
   rotation (no mainline support).

The IROM domain is marked as always enabled as we should arrange for it
to be enabled when we suspend which will need a bit more work.

Due to all the conditional device registration that the platform does
wrap s3c_pm_init() with s3c64xx_pm_init() which actually puts the device
into the power domain after the machines have registered, looking for
platform data to tell if the device was registered. Since currently only
Cragganmore actually sets up PM that is the only machine updated.

CODEC daughtercard. Provide standard support for the use of WM8994 class
devices on the Littlemill card, configuring the MFD for WM8958 usage as
this part is a superset of all others and the driver will use runtime

The Cragganmore system is modular with I2C based identification chips on
the system allowing identification of the system build. Provide a stub I2C
driver which parses the module IDs and uses them to select the appropriate
audio subsystem components to register. To avoid confusion due to having
the mini-driver in the system the driver is placed in a separate file.

The original Cragganmore code was submitted while new code was being
refused for mainline. This patch was unexpectedly merged upstream but
development had continued in the expectation that the code would be
resubmitted later so no split patches were maintained. This patch
synchronises that work with the recently merged driver.

The main changes are fleshing out of the PMIC and audio integration for
the system, including addition of the Dallas Dhu and Tobermory audio
modules, plus some minor updates to account for revision 2 hardware.

The Cragganmore carrier card and Banff CPU module are used on Wolfson
Microelectronics reference systems.  This initial support covers the
core system which is a fairly generic S3C6410 based design, further
patches will add support for the key features of the reference system.

The initial board bringup and therefore much of the key code was done by
Ben Dooks for Simtec, with additional work (especially around the
integration of the Wolfson devices) being done by myself.
