drm/amd/display: Correct output color space during HW reinitialize
[Why]
Doing core_link_disable_stream or set_dpms_off when reinitializing
hardware causes issue to repro with external display connected. This is
unnecessary, blanking pixel data should be sufficient.
[How]
Call disable_pixel_data while reinitializing hardware instead of
core_link_disable_stream or set_dpms_off.
