drm/amd/display: Copy crc_skip_count when duplicating CRTC state
[Why]
crc_skip_count is used to track how many frames to skip to allow the OTG
CRC engine to "warm up" before it outputs correct CRC values.
Experimentally, this seems to be 2 frames.
When duplicating CRTC states, this value was not copied to the
duplicated state. Therefore, when this state is committed, we will
needlessly wait 2 frames before outputing CRC values. Even if the CRC
engine is already warmed up.
[How]
Copy the crc_skip_count as part of dm_crtc_duplicate_state.
