There are a number of statements of the form A, B or A, B, C where
the numbers A,B,C are not consecutive. However, referencing [1] it
is the correct thing to replace these with A-B or A-C as apropriate.

Fix the link errors if cpu-frequency support is enabled on s3c2410 systems
but there is no CONFIG_S3C2410_IOTIMING set. Fix this by ensuring the
relevant symbols are defined NULL if the code is not being built in.
Fixes the following error:
arch/arm/mach-s3c2410/built-in.o: undefined reference to `s3c2410_iotiming_get'
arch/arm/mach-s3c2410/built-in.o: undefined reference to `s3c2410_iotiming_set'

Add better support for omitting either the card detect or the write
protect GPIOs if the board does not support it. Add the fields
no_wprotect and no_detect to the platform data which when set indicate the
absence of the respective GPIOs.
Note, this also fixes a minor bug where it tries to free IRQ0 if there is
no detect gpio available.

Add a selection for the data transfer mode of the s3cmci driver, allowing
for either a configuration or rumtime selection of the use of the DMA or
PIO transfer code.
The PIO only mode is 476 bytes smaller than the driver with both methods
compiled in.

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.

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.

TCFG divider settings and provide any other per-arch data that the
pwm-clock driver needs to function.

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.
