include/device/azalia_device.h: Add enum for misc field
The HDA specification defines bits 11:8 of the Configuration Default register as a miscellaneous field for other jack information. Only bit 8 has a standard meaning, and indicates that the jack does not have presence detect capability. Add an enum for use in the AZALIA_PIN_DESC macro to indicate this field. Note that many vendor firmwares set bits 11:9 to non zero values despite them being reserved in the specification, and their meaning in these cases is not well known.
