ALSA: hda - Fix bad EAPD setup for HP machines with AD1984A
It seems that EAPD on NID 0x16 is the only control over all outputs on HP machines with AD1984A while turning EAPD on NID 0x12 breaks the output. Thus we need to avoid fiddling EAPD on NID. As a quick workaround, just set own_eapd_ctrl flag for the wrong EAPD, then implement finer EAPD controls.
