This patch allows bypassing most of legacy initialization when booting
an S3C64xx-based board using device tree, by adding conditional checks
for DT presence to initcalls which are no longer necessary when booting
with DT..

Since commit 7ed76e08 (ARM: EXYNOS: Fix low level debug support)
map_io() is not needed for exynos5440 so need to fix to lookup
cpu which using map_io(). Without this, kernel boot log complains
'CPU EXYNOS5440 support not enabled' on exynos5440 and panic().

This patch removes legacy UART initialization code that was used to
set up UART platform devices when booting with ATAGS, which is not
supported on Exynos any more.

This patch fixes CPU idmask of S5P64X0 and EXYNOS4210
and its comparison method because just want to use CPU
id for it.

Move the init.c and time.c files to plat-samsung from plat-s3c, thus
clearing the last files that are being built in here.

As per Russell King's last review comment, find and remove

Fix the usage of CONFIG_SERIAL_SAMSUNG_UARTS in several places
in the kernel where it had been missed. This finishes fixing a
long standing issue where S3C2443 and S3C64XX could not use the
4th UART

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.
