Vendor specific D5 power state, only entered once the part is already in D3cold
(this bit must be set before the command to enter D3cold). If set, this bit over-
rides the D4 bit (bit 0). Includes the power savings of D4, but additionally pow-
ers down GPIO pins, the VAG amp, and the HP amps. Exits this power state
via POR or rising edge of Link Reset.
