Move the low-level SoC-specific clockdomain control functions into cm*.c and prm*.c. For example, OMAP2xxx low-level clockdomain functions go into cm2xxx.c. Then remove the unnecessary clockdomain*xxx*.c files. The objective is to centralize low-level CM and PRM register accesses into the cm*.[ch] and prm*.[ch] files, and then to export an OMAP SoC-independent API to higher-level OMAP power management code.
