mb/google/trulo/var/pujjolo: Update verb table to fix pop noise

Browse source 
Because there is a pop noise when bios booting stage, so modify
verb table to fix the issue.

Change description by vendor:
The Class-D K DC function has been added (which is the main solution
this time), along with enabling silence detect to filter out noise
below -84 dB to prevent it from being played through the speaker.

BUG=b:430749506
TEST= Build and boot to OS, and check by EE and Realtek vendor.
