Would it be better to have this changed to:
	select COMMON_CLK_PALMAS if MFD_PALMAS
instead of removing.

All OMAP5 boards uses Palmas as PMIC and the boards where twl6040 audio is in
use the 32K clock for the codec is coming from Palmas.
Without this clock the twl6040 will not boot up causing errors during probe time.
