ASoC: SDCA: Add correct masks whilst reporting SDCA jack status

Browse source

Currently, all SDCA jacks simply report against a mask of 0xFFFF. This
works fine for system with a single SDCA jack control as the status
reflects that single control at all times. However, if two SDCA
jack controls exist in the system, such as a separate representation for
input and output, then the second control can cancel reports from the
other since it will only report its relevant bits and zero in all other
slots. This is exactly what the mask is for.

Build up a mask using all the possible states for an SCDA jack control
at registration time and use that mask when reporting a particular jack.
It is worth noting this still doesn't handle cases such as two headphone
jacks as that would require separate ALSA jacks to report to.
