[PATCH 12/16] drm/amd/display: Copy crc_enabled when duplicating dm_crtc_state

[sunpeng.li at amd.com]

From: Nicholas Kazlauskas <nicholas.kazlauskas at amd.com>

[Why]
When running igt at kms_plane@pixel-format-pipe-* tests the CRC read will
time out and the test will fail.

This is because the CRTC is duplicated but the crc_enabled parameter
isn't copied over to the new dm_crtc_state. CRC reads will time out
because amdgpu_dm_crtc_handle_crc_irq will no longer call
drm_crtc_add_crc_entry.

[How]
Copy crc_enabled when duplicating the state.
