[PATCH AUTOSEL 5.10 04/10] ALSA: hda/conexant: fix Z60MR100 startup pop issue

From: bo liu <bo.liu@senarytech.com>

[ Upstream commit 947c4012f8f03a8bb946beb6e5294d5e32817d67 ]

When Z60MR100 startup, speaker will output a pop. To fix this issue,
we mute codec by init verbs in bios when system startup, and set GPIO
to low to unmute codec in codec driver when it loaded .

[ white space fixes and compile warning fix by tiwai ]
