Wenjing Liu c443514a7d drm/amd/display: lower lane count first when CR done partially fails in EQ 
[why]
According to DP specs, in EQ DONE phase of link training, we
should lower lane count when at least one CR DONE bit is set to 1, while
lower link rate when all CR DONE bits are 0s. However in our code, we will
treat both cases as latter. This is not exactly correct based on the specs
expectation.

[how]
Check lane0 CR DONE bit when it is still set but CR DONE fails,
we treat it as a partial CR DONE failure in EQ DONE phase, we
will follow the same fallback flow as when ED DONE fails in EQ
DONE phase.
