ARM: OMAP2+: CM: add common API for cm_wait_module_ready

This patch consolidates the parameters provided for the SoC specific
cm_*_wait_module_ready calls, adds the missing cm_ll_data function
pointers and uses the now generic call from the mach-omap2 board code.
SoC specific *_wait_module_ready calls are also made static so they
can only be accessed through the generic CM driver API only.
