ASoC: OMAP4: Make supported sample rates and clock gating dynamic
- Instead of requiring the BSP to deliver a list of clock
dividers and an expected fClk rate, simply compute the
rates which can be produced from the provided fClk at
runtime.
- Instead of requiring the BSP to enable the fClk and leave
it enabled at all times, have the driver enable and
disable the clock when it is needed in an attempt to save
some power.
