The "da" and "hc" type boards have normal analog outputs. The "ao"
type boards have move advanced analog outputs with waveform generation
capability.
Replace the 'ao_ability' member of the boardinfo with some bit-field
flags, 'has_ao' and 'has_wform_ao', and only set them appropriately
based on the board type.
