Move the core S3C64XX support to mach-s3c64xx as it is unlikely to be used
outside of this directory. Also move the SoC header files in with it.

This includes the clock, cpu, cpufreq, dma, gpiolib and pll support.

Move the register and GPIO definition files from plat-s3c64xx into the
machine include direcotry as they are unlikely to be reused outside
mach-s3c64xx.

This move includes removing the empty <mach/regs-clock.h> and replacing
it with the <plat/regs-clock.h> implementation.

Add s3c_register_clocks() to register an array of clocks, printing
an error message if there is a problem. Replace all points in the code
where this could be used.

The usb-host clock was using the wrong define (the SCLK enable for the
usb-host-bus) to change the HCLK register instead of the HCLK_UHOST bit.

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 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.

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