[PATCH 14/21] clk: samsung: clk-gs101: add CMU_APM support

[Peter Griffin <peter.griffin@linaro.org>]

This patch adds all the registers for the APM clock controller unit.

We register all the muxes and dividers, but only a few of the
gates currently for PMU and GPIO.

One clock is marked CLK_IS_CRITICAL because the system
hangs is this clock is disabled.
