As per Russell King's last review comment, find and remove
all unnecessary includes of <linux/delay.h> in the files
that do not need them.

The commit 39263db7986bf15c753f6847699107bdf5a2e318 added
a default <mach/io.h> implementation which is shared if
needed between all the s3c implementations. Remove the
s3c24a0 version which is the same as this.

The changes for ARM highmem support have removed the need
for the __virt_to_bus and __bus_to_virt macros, so remove them
from this build.

Add the fourth UART definition for the S3C2443, and at the
same time fixup the problems caused by the enlarging of the
UART array in the previous commits.

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

Add a configuration option to start the UART FIFOs during the
decompressions sequence to improve boot time when the bootloader
fails to enable the UART FIFOs.
For example, the SMDK6410 UBoot 1.1.6 leaves the FIFOs off.

The S3C64XX timer is running at the wrong rate due to the
assumptions made in the timer initialisation about the way
the pwm dividers work. This means that time on the S3C64XX
runs twice as fast as it should.
Fix the problem by moving to using the clk framework to setup
the pwm timer clock muxes, as the pwm-clock code has all the
necessary knowledge of how the timer clock inputs are routed.

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.
