Subject: drm/amd/display: Incorrect Read Interval Time For CR Sequence
Git-commit: 0430017149c53f20493ebeee856315c669d18f4d
Patch-mainline: v5.4-rc1
References: bsc#1152489

[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.
