apalis-imx8qm: add audio support through SGTL5000 codec
Add SAI1 I2S peripheral and SGTL5000 audio codec support for
on-module audio support. Note that clocking is currently setup
in the SGTL5000 codec node, altough it seems that due to cross
dependencies those clocks (or root clocks thereof) might get
changed later on. With the current clock frequencies audio
seems to play at the correct rate.
The power rails need further refinement.
