Add apropriate enable call for clk_48m.

The clk_fout_epll clock wasn't registered as part of the initial clock
work, which can cause problems if it is used by one of the hardware
blocks.

Add new GPIO configuration calls that mesh with the
new gpiolib support.

Add gpiolib registration for the GPIOs available on the
S3C64XX platform

The gpiolib driver keeps its chip array to itself
and having a separate array for s3c-only gpios stops
any non-s3c gpio being used in one of the s3c specific
configuration calls.

Add definitions for the external interrupt groups which accompany
the original IRQ_EINT from the s3c24xx series.

Discard the 'void *' from the pointers used for the
virtual addresses when setting up the .virtual fields
of the io map to avoid implicit cast warnings

Some of the startup output can be reduced to
KERN_DEBUG from KERN_INFO as it is only really
useful when trying to debug kernel initialisation
problems.

Add the necessary code to support IRQ_EINT(x) on
the S3C64XX series of CPUs.
Note, since there is no GPIO configuration support
in the kernel, the irq set_type method does not
configure the relevant pin to interrupt.

Add demux handling for the UART interrupts
generated by the VIC into their seperate IRQs
that the serial driver can register.

Add the PLL clock initialisation and clock registration
and include the clocks sourced via CLKDIVx for most of
the on-chip peripherals.

Add the initial clocks definitions for the s3c6400
and s3c6410. Move the epll and ext clock from the
s3c2443 support into the common code.

S3C6400 and S3C6410, the UART registration.

Initialise the basic physical to virtual mappings and
then detect the CPU that the system is being run on so
that the cpu code code can call the correct initialisation
code.

Add the initial header files for the S3C64XX support to satisfy the
minimal requirements to build a kernel. Some definitions will therefore
be placeholders or empty functions that will ensure that the system can
build and have base functionality. These will be filled in at a later
date.
