mb/google/link: Enable HP jack output under Windows
The EAPD pin needs to be enabled and set in order for the headphone
jack to work properly. It's already done for the speaker in the
beep verbs, but needs to be done for the HP jack as well in order
for output to work properly under Windows.
TEST=build/boot Win11 on LINK, verify headphone output functional
when headphones plugged in.
