mb/google/fatcat/var/francka: Disable ALC721 & ALC722 clock stop support

Browse source 
This change allows flag to be override via devicetree,
instead of relying on the default value in alc711_slave.
It helps fix the missing event issue when plugging or
unplugging the 3.5mm headphone jack.

BUG=b:417133565, b:420516709
TEST=Verified build and boot with ALC721 and ALC722.
Headphone path switches successfully via audio jack event.
Confirmed SSDT dump at PCI0.HDAS.SNDW.
