mb/google/nissa/var/anraggar: Set EN_SPK_PA to low to avoid noise

In order to avoid the noise caused by the codec output to the audio
jack during the shutdown and poweron process, we will use GPP_A11 for
the codec power supply gate, keep low during the startup process, and
wait for the driver to turn on. This change does not affect the beep
output of depthcharge.

BUG=None
TEST=There is no squeaking sound when turning on and off
