This patch introduces common.[ch] which are used only in the
arch/arm/mach-s3c64xx/ directory. The common.c file merges
the cpu.c, irq.c and irq-eint.c which are used commonly on
S3C64XX SoCs and the common.h file replaces with plat/s3c6400.h
and plat/s3c6410.h files.

Some boards based on S3C6410 use synchronous clocking, which means that HCLKx2
and other system clocks are generated from APLL instead of MPLL.

This patch adds support for such boards, by calculating hclk2 depending on
the status of S3C_OTHERS_SYNCMUXSEL bit in S3C64XX_OTHERS regist

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.
