ASoC: apple: mca: increase SERDES reset delay
The SERDES clusters in this peripheral take a long time to warm up.
We tried polling the reset bit until cleared, however this is not
a reliable signal of readiness to be configured. Only waiting
~25 us to give the cluster a chance to settle makes it work
reliably.
Increase the 2 us delay to 25 us and hope we never have to do this
again.
