arm64: dts: imx8mp-msc-sm2s: Add sound card
The MSC SM2-MB-EP1 carrier board for the SM2S-IMX8PLUS SMARC module has an
NXP SGTL5000 audio codec connected to I2S-0 (sai2).
This requires to:
* add the power supplies (always on)
* enable sai2 with pinmuxes
* reparent the CLKOUT1 clock that feeds the codec SYS_MCLK to
IMX8MP_CLK_24M in order it to generate an accurate 24 MHz rate
