3.5.7.27 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Nicolin Chen <b42378@freescale.com>
commit 50bfcf2df2fadf77e143d6099150e6fa7ef4d78c upstream.
It's safer to turn on regcache_cache_only before disabling regulator since the driver will turn off the regcache_cache_only after enabling regulator.
If we remain cache_only false, some command like 'amixer cset' would get failure if being run before wm8962_resume().
