ASoC: sgtl5000: Fix noise on shutdown/remove
[ Upstream commit 040e3360af3736348112d29425bf5d0be5b93115 ]
Put the SGTL5000 in a silent/safe state on shutdown/remove, this is
required since the SGTL5000 produces a constant noise on its output
after it is configured and its clock is removed. Without this change
this is happening every time the module is unbound/removed or from
reboot till the clock is enabled again.
The issue was experienced on both a Toradex Colibri/Apalis iMX6, but can
be easily reproduced everywhere just playing something on the codec and
after that removing/unbinding the driver.
Fixes: 9b34e6cc3bc2 ("ASoC: Add Freescale SGTL5000 codec support")
