include/device/azalia_device.h: Add enum for misc field

Browse Source 
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.
