Convert the OMAP2xxx APLL code to use omap2_cm_wait_module_ready(), and move the low-level CM register manipulation functions to mach-omap2/cm2xxx.c. The objectives here are to remove the dependency on the deprecated omap2_cm_wait_idlest() function in mach-omap2/prcm.c, so that code can be removed later; and move low-level register accesses to the CM IP block to the CM code, which will soon be moved into drivers/.
