EAPD bit is set to one by default but the EAPD state is 0 after power-on reset because the function group is not in D0. The
state after a single or double function group reset will be compliant with HDA015-B.

Defines if EAPD pin is used as input, output, or bi-directional port (Open Drain)
0 = Amp controlled by EAPD pin only (default) / 1 = Amp controlled by power state (pin and FG) only
0 = Amp will mute when disabled. (default for ZA and ZB only) / 1 = Amp will shut down (enter a low power
state) when disabled (default for YA forward)
0 = AMP will power down (or mute) when EAPD pin is low (default) / 1 = Amp will power down (or mute)
when EAPD pin is high.
