ASoC: codecs: Remove unused rt566[58]_sel_asrc_clk_src

Browse source 
rt5665_sel_asrc_clk_src() was added in 2016 by
commit 33ada14a26 ("ASoC: add rt5665 codec driver")

rt5668_sel_asrc_clk_src() was added in 2018 by
commit d59fb28562 ("ASoC: rt5668: add rt5668B codec driver")

Neither have been used.

Remove them.

*
* The ASRC function is for asynchronous MCLK and LRCK. Also, since RT5665 can

* support special i2s clock format such as Intel's 100fs(100 * sampling rate).
* ASRC function will track i2s clock and generate a corresponding system clock
* for codec. This function provides an API to select the clock source for a
* set of filters specified by the mask. And the codec driver will turn on ASRC
* for these filters if ASRC is selected as their clock source.
