drm/amd/display: Switch ddc to new aux interface
[Why]
The old aux interface goes through i2caux and the aux_engine
and engine function pointers. The multiple layers of indirection
make it hard to tell waht is happening. The aux algorithm
does not need to be this complicated: attempt to submit the
request. If you get an ack (reply = 0), stop. Otherwise,
retry, up to 7 times.
[How]
Add a new helper function in dce_aux that performs aux retries
Move the plumbing of the aux calling code into dce_aux
Add functions in ddc that redirect directly to dce_aux
Make all aux calls use these functions
