Split the timer pending code out to a seperate per-machine
header so that when compiling for mach-s3c2410 or mach-s3c24a0
we can use the right timer code without having to #ifdef the
timer driver.

Initial architecture support for the S3C24A0 ARCH_S3C24A0.
We don't yet add an kconfig entry in the main arch/arm/Kconfig
file as the series is not complete, so that is left until enough
support is in to be useful.

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.

The pwm-scaler0 and pwm-scaler1 clocks have their
.id field set to -1 as they are not referenced to
any specific device. However, parts of the pwm-clock
code used the .id field to identify which scaler
clock was being used.
Fix the problem by comparing against the pointer to
the clock to identify the scalers.

All the s3c24xx gpiolib chips share the same get/set
calls and all but one bank shares the same calls for
.direction_input and .direction_output methods.
Change the initialisation process to use an new call
to register the chips that fills in any blank calls
with the default values to avoid having to fill them
in the structure initialisers.

Add a simple check when registering a clock on whether
the clock has already been added to the list.
Any attempt to re-register a clock will cause the
clock list to be come looped and thus produces silent
failures when looking up clocks.

Only certain boards need these clocks, and they are not
available on some CPUs (such as the S3C24A0) so remove
them from arch/arm/plat-s3c24xx/clock.c and into their

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.

We were missing the CPU_FTR_NOEXECUTE bit in our cputable for all
these processors. The result is that update_mmu_cache() would flush
the cache for all pages mapped to userspace which is totally
unnecessary on those processors since we already handle flushing
on execute in the page fault path.
This should provide a nice speed up ;-)
