drm/amd/display: Incorrect Read Interval Time For CR Sequence
[WHY]
TRAINING_AUX_RD_INTERVAL (DPCD 000Eh) modifies the read interval
for the EQ training sequence. CR read interval should remain 100 us.
Currently, the CR interval is also being modified.
[HOW]
lt_settings->cr_pattern_time should always be 100 us.
