drm/amd/display: Shift dc link aux to aux_payload
[Why]
aux_payload should be the struct used inside dc to start
aux transactions. This will allow the old aux interface
to be seamlessly replaced.
[How]
Add three fields to aux_payload: reply, mot, defer_delay
This will mean that aux_payload has all data required
to submit a request. Shift dc_link to use this struct
