OMAP2/3 clock: split, rename omap2_wait_clock_ready()
Some OMAP2/3 hardware modules have CM_IDLEST attributes that are not
handled by the current omap2_wait_clock_ready() code. In preparation
for patches that fix the unusual devices, rename the function
omap2_wait_clock_ready() to omap2_wait_module_ready() and split it
into three parts:
1. A clkops-specific companion clock return function (by default,
omap2_clk_dflt_find_companion())
2. A clkops-specific CM_IDLEST register address and bit shift return
function (by default, omap2_clk_dflt_find_idlest())
3. Code to wait for the CM to indicate that the module is ready
(omap2_cm_wait_idlest())
Clocks can now specify their own custom find_companion() and find_idlest()
functions; used in subsequent patches.
