mb/google/fatcat/var/moonstone: Disable RT721 clock stop support

Browse source 
RT721 headset jack detection fails because the wakeup event is not
triggered during runtime suspend in D3 state. Disable the clock stop
to allow the bus driver to handle the wakeup process properly. The MIPI
Disco property is "mipi-sdw-simplified-clockstopprepare-sm-supported".

BUG= b:435094908
TEST= verify headset jack works properly.
