ARM: OMAP2+: CM/clock: convert _omap2_module_wait_ready() to use SoC-independent CM functions
Convert the OMAP clock code's _omap2_module_wait_ready() to use SoC-independent CM functions that are provided by the CM code, rather than using a deprecated function from mach-omap2/prcm.c. This facilitates the future conversion of the CM code to a driver, and also removes a mach-omap2/prcm.c user. mach-omap2/prcm.c will be removed by a subsequent patch. Some modules have IDLEST registers that aren't in the CM module, such as the AM3517 IDLEST bits. So we also need a fallback function for these non-CM odd cases. Create a temporary one in mach-omap2/clock.c, intended to exist until the SCM drivers are ready. Signed-off-by: Paul Walmsley <paul@pwsan.com> Tested-by: Vaibhav Hiremath <hvaibhav@ti.com>
