ALSA: hda - Fix AFG power management on IDT 92HD* codecs
The AFG pin power-mapping isn't properly set for the fixed I/O pins on IDT 92HD* codecs. This resulted in the low power mode after the boot until any jack detection is executed, thus no output from the speaker. This patch fixes the power mapping for the fixed pins, and also fixes the GPIO bits and digital I/O pin settings properly in stac92xx_ini().
