Some of the rate selection logic in s3c64xx_setrate_clksrc uses what
appears to be parent clock selection logic. This patch corrects it.

I also added a check for overly large dividers to prevent them from
changing unrelated clocks.

arch_initcall() runs after the machine init function which means that
any configuration of GPIO pins must currently be done later on, for
example in callbacks from drivers. Move the initialisation earlier in
order to allow machines to configure GPIOs directly in their init
functions rather than having to have a callback invoked later on.

Some other ARM platforms use this method. Other solutions for this
include providing a special interface for setting up GPIOs en masse,
adding callbacks to do the GPIO configuration from devices and doing
the GPIO configuration implicitly.

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.
