[PATCH] ALSA: hda/realtek: Fix quiet 3.5mm jacks on Beelink SER6

Both the front headphone jack and the rear line-out jack play back
at a barely audible volume on the Beelink SER6 Max (ALC897, PCI subsystem
ID 1f66:0202), even with all mixer controls at 0dB. GPIO2 on the
codec gates an external headphone/line amplifier that the generic
parser never enables. Add a fixup that asserts it. Verified fixed
on both jacks.
