device/azalia_device.c: Add codec reset helpers

Browse source 
Many uses of `azalia_set_bits` are used to toggle the reset bit. To
avoid having to repeat the register operations and the corresponding
comment, create two helpers with self-explanatory names. They will be
put to use in subsequent commits, with one change for each function.
