drm/amd/display: Fix ODM combine issue with fast boot 

[Why]
When systme power up and eDP lit up by VBIOS,
in the core_link_enable_stream(),
the function will early return due to apply
apply_edp_fast_boot_optimization,
resulting the DP_PIXEL_COMBINE cannot get set
in enc3_dp_set_odm_combine.

[How]
Check ODM PIPE to avoid early return.
