ALSA: hda - Keep EAPD turned on for old Conexant chips
commit 254f296840b64b034a4c850d45dbde7c040f0819 upstream.
In the old Conexant chips (5045, 5047, 5051 and 5066), a single EAPD
may handle both headphone and speaker outputs while it's assigned only
to one of them. Turning off dynamically leads to the unexpected silent
output in such a configuration with the auto-mute function.
Since it's difficult to know how the EAPD is handled in the actual h/w
implementation, better to keep EAPD on while running for such codecs.
