mb/google/ocelot/var/ocelot: Disable ALC721 clock stop support

Browse source 
This change allows flag to be overridden 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.

TEST=Verified build and boot with ALC721.
Headphone path switches successfully via audio jack event.
