This adds sound support to the Reform2.
It differs from the downstream implementation in that the codec
is used as the BCLK and FSYNC master and the i.MX8MQ only supplies
a fixed 25MHz MCLK from the oscillator. This allows to support
a wider range of audio rates by using the codec PLL and to shut
down the audio PLLs on the i.MX8MQ SoC side.
