ARM: msm: Make proc_comm clock control into a platform driver
To move closer to the generic struct clock framework move the
proc_comm based clock code to a platform driver. The data
describing the struct clks still live in the devices-$ARCH file,
but the clock initialization is done at driver binding time.
