ASoC: codecs: es8375: use devm_clk_get_optional() for mclk

es8375_read_device_properities() gets "mclk" with devm_clk_get() and
then tests the result for NULL to print "assuming static mclk". A
missing clock makes devm_clk_get() return -ENOENT, so the probe fails
before that test can match.

The binding does not require clocks, its example has none, and
everest,mclk-src lets the codec run from SCLK instead of MCLK. Use
devm_clk_get_optional(), as es8311, es8316, es8323, es8326 and es8389
do for the same clock.

Found with an experimental clang warning about NULL tests on functions
that return error pointers. Tested only in QEMU with i2c-stub in place
of the codec, not on real hardware.
