[Sean Paul]

Fixes the following link error when CONFIG_DRM_ANALOGIX_DP is not defined:

ERROR: "analogix_dp_start_crc" [drivers/gpu/drm/rockchip/rockchipdrm.ko] undefined!
ERROR: "analogix_dp_stop_crc" [drivers/gpu/drm/rockchip/rockchipdrm.ko] undefined!

Fixes: 3190e58dafaf ("drm/rockchip: Implement CRC debugfs API")

Similar to 3/3 adding stubs for
analogix_dp_start_crc/analogix_dp_stop_crc will be shorter/cleaner
than ifdef spaghetti.

At the same these fix the problems so, for the series:

Thanks for the review, Emil.

I think given that there's only one driver that supports crc in
rockchip-land, it makes sense to target that driver specifically.
If/when there is more than one, I agree we should have a shim/stub.

That said, if Tomeu or anyone else wants to follow on with an ifdef
cleanup, I'm happy to review.
