Current code has duplicate code for 16000, 32000 and 48000 sample rates.
get_srate() returns negative error code for unsupported rate, so we can
remove the duplicate code in the swith cases by calling get_srate() first.

Now that we have a codec_probe stage initialization in the wm_adsp

Currently the only init function in wm_adsp is called by the
codec driver early in its probe before the codec has been
registered with SOC.

This patch adds stubs for the codec_probe and codec_remove stages
and calls them from WM5102 and WM5110 codec drivers. This allows us
to hang anything that needs setup during the codec probe stage off
these functions without further modification of the codec drivers.

Implement hardware constraint handling towards the pll_clkin:
if D != 0 (in J.D) then 1.1MHz <= pll_clkin <= 9.2MHz needs to be checked.

reference clock, if BCLK fails, use the internal 1.8MHz clock.
