Change the way the UART state is saved over suspend to allow the s3c64xx
code to modify the settings on resume to avoid any illegal state changes
to the UART clocks. This will also allow us to save the UDIVSLOT register
on newer SoCs.
Move to using a structure for the UART use the extant Kconfig configuration
specifying the number of UARTs.

Move the IRQ_EINT sleep control to be available to all
s3c impelmentations. Since s3c_irqext_wake is not large,
place it in arch/arm/plat-s3c/pm.c as adding it to a new
file would be a waste of compile time.

Split the PM code out of arch/arm/plat-s3c24xx/irq.c to
remove some of the #ifdefs being used. Also fix a couple
of places where the absecnce of a function was redefined
to the same thing.

Move the <plat/pm.h> header to plat-s3c as preparation

The S3C64XX series has a new TCFG divider setting to allow the clock
directly through, which means that we need to update the pwm-clock
code to cope with this.
Add <mach/pwm-clock.h> containing the specific code to deal with the
TCFG divider settings and provide any other per-arch data that the
pwm-clock driver needs to function.

Split the map.h definitions into common S3C24XX code by
adding arch/arm/plat-s3c24xx/include/plat/map.h and
altering the machine specific header for the S3C24A0.
As we add a new <plat/map.h> we move the original one
in arch/arm/plat-s3c include directory to be called
map-base.h to distinguish the two files.

Update the clock settings on resume for suspend/resume
support so that if the boot loader changes anything or
the system's PLL is reset then we return with the correct
settings.

We cannot sleep if we have cpufreq pm enabled during some
of the clock operations, so change to use a spinlock to
protect the clock system.

Move the PLL calculation code into it's own header
file for re-use with the other plat-s3c24xx based
systems such as the S3C24A0.
Note, we change the name of s3c2410_get_pll to the
more generically named s3c24xx_get_pll as well as
the related defintions.

We need to add plat-s3c to the build to get the headers
that will go in here once moved from include/asm-arm so
we may as well put some useful common s3c code in here
to stop the errors generated form having nothing built.
The cpu setup is now passed the cpu idcode and the table
of supported cpus to s3c_init_cpu() to abstract the
cpu identification out of the initial io setup.
As well as moving the cpu initialisation code, we move the
map of the board specific items up to the calling code as
none of the map_io() functions actually do anything other
than pass this to iotable_init().
This patch does not rename any of the init functions that
will be common to s3c24xx and any other s3c architectures
as this can be done at a later date as it will touch all
the board support files which use functions such as
s3c24xx_init_clocks() and s3c24xx_init_uarts().
Note, the header arch/arm/plat-s3c24xx/include/plat/cpu.h
still has functions that are used by both the cpu and
board initialisation functions. This means that each board
has definitions specific to the cpu support included and
the vice-versa.

First move of items out of include/asm-arm/plat-s3c* to their
new homes under arch/arm/plat-s3c/include/plat and
arch/arm/plat-s3c24xx/include/plat directories.
Note, we have to create a dummy arch/arm/plat-s3c/Makefile to
allow us to add arch/arm/plat-s3c/include/plat to the path.
