[PATCH] arm/mach-pxa: add CCCR bits definitions

Add CCCR bits definition for PXA SoC, so that the bootloader
can setup a stable core clock frequency, which is not the
initial reset clock, as required by Intel's PXA27x Processor
family developer's guide, chapter 3.5.5, table 3.7 (clock
frequencies).
