Testing mach-rk3188 clock_data into mach-rk30

Since clock_data is missing in mach-rk30 (even though we have
clock_data.uu from previous rk30 kernels) and given that rk31's
clock_data.c mentions rk30 compatibility:

This commit is for copying into mach-rk30 the files:
mach-rk3188/clock_data.c
mach-rk3188/include/mach/cru-rk3188.c

(rename your mach-rk30/clock_data.uu and .o for changes to take effect)
Changes to rk31's clock_data.c to compile kernel for rk30

Compilation works, but kernel hungs on startup
