Now we've move the support out of plat-s3c64xx for everything, eliminate
the platform directory arch/arm/plat-s3c64xx and remove it from the ARM
build configuration.
Note, PLAT_S3C64XX is kept around for the moment until the drivers that
depend on it can be updated, so it is moved to the mach-s3c64xx Kconfig.

Merge plat-s3c64xx/s3c6400-clock.c mach-s3c64xx/clock.c placing all the
clock code into one place.
Note, no effort is made in this patch to squash the init functions
together.

Since this file is small, and is compiled for both systems in this
architecture merge it into the cpu support file and remove the original
instead of moving it.

Move the core S3C64XX support to mach-s3c64xx as it is unlikely to be used
outside of this directory. Also move the SoC header files in with it.
This includes the clock, cpu, cpufreq, dma, gpiolib and pll support.

Platform devices for SPI Controller of S3C64XX are defined and exported for
machines to include. Also, controller setup helper functions are defined for
machine code to set runtime configuration of the controller and the bus.

This patch provides initial support for CPU frequency scaling on the
Samsung S3C ARM processors. Currently only S3C6410 processors are
supported, though addition of another data table with supported clock
rates should be sufficient to enable support for further CPUs.
Use the regulator framework to provide optional support for DVFS in
the S3C cpufreq driver. When a software controllable regulator is
configured the driver will use it to lower the supply voltage when
running at a lower frequency, giving improved power savings.
When regulator support is disabled or no regulator can be obtained
for VDDARM the driver will fall back to scaling only the frequency.

Add support for the DMA blocks in the S3C64XX series of CPUS,
which are based on the ARM PL080 PrimeCell system.
Unfortunately, these DMA controllers diverge from the PL080
design by adding another DMA controller register and
configuration for OneNAND.

Add support for saving the state of the IRQ registers over suspend.
This requires moving the S3C64XX UART registers into <plat/regs-serial.h>
and adding irq-pm.c which saves the state of all the IRQ registers.
The irq-pm.c saves all the IRQ registers, including the IRQ_EINT and
IRQ_EINT_GROUP registers as it was easier than adding three different
files. Also ensuring that all the registers are restored to the same
state as before suspend is considered to be the best thing to do.
Note, we do not suspend the VIC here, this is done by the VIC driver
itself.

Add the necessary code to support IRQ_EINT(x) on

Note, since there is no GPIO configuration support
in the kernel, the irq set_type method does not
