mfd: dt-bindings: ab8500: Describe codec graph and microphone wiring
The AB8500 and AB8505 codec block exposes two digital audio
interfaces. Define the codec as a one-cell sound DAI provider and allow
it to expose both interfaces as audio graph ports.
The codec binding conversion also omitted the analog microphone type
and bias-routing properties supported by the driver and documented by
the old text binding. Restore them so boards can describe the codec
wiring without schema warnings.
