Subject: [PATCH] ASoC: wm8962: Redo early init of the part on resume

commit e4dd76788c7e5b27165890d712c8c4f6f0abd645 upstream.

Ensure robust startup of the part by going through the reset procedure
prior to resyncing the full register cache, avoiding potential intermittent
faults in some designs.
