ASoC: apple: mca: Fix final status read on SERDES reset
[ Upstream commit aaf5f0d76b6e1870e3674408de2b13a92a4d4059 ]
From within the early trigger we are doing a reset of the SERDES unit,
but the final status read is on a bad address. Add the missing SERDES
unit offset in calculation of the address.
