ASoC: max98090: Fix reset at resume time
commit 25b4ab430f8e166c9b63f4db28e7e812d5a59396 upstream.
Reset needs to wait 20ms before other codec IO is performed. This wait
was not being performed. Fix this by making sure the reset register is not
restored with the cache, but use the manual reset method in resume with
the wait.
