ASoC: codecs: Remove unused rt566[58]_sel_asrc_clk_src
rt5665_sel_asrc_clk_src() was added in 2016 by
commit 33ada14a26c8 ("ASoC: add rt5665 codec driver")
rt5668_sel_asrc_clk_src() was added in 2018 by
commit d59fb2856223 ("ASoC: rt5668: add rt5668B codec driver")
Neither have been used.
Remove them.

1034
-
* ASRC function will track i2s clock and generate a corresponding system clock
1035
-
* for codec. This function provides an API to select the clock source for a
1036
-
* set of filters specified by the mask. And the codec driver will turn on ASRC
1037
-
* for these filters if ASRC is selected as their clock source.
