/display: Not to call dpcd_set_source_specific_data
during resume.
[Why]
During resume path, dpcd_set_source_specific_data is taking
extra time when core_link_write_dpcd fails on DP_SOURCE_OUI+0x03
and DP_SOURCE_MINIMUM_HBLANK_SUPPORTED. Here,aux->transfer fails
with multiple retries and cons
[Why]
During resume path, dpcd_set_source_specific_data is taking
extra time when core_link_write_dpcd fails on DP_SOURCE_OUI+0x03
and DP_SOURCE_MINIMUM_HBLANK_SUPPORTED. Here,aux->transfer fails
with multiple retries and consume sigficantamount time during
S0i3 resume.
[How]
Not to call
