[PATCH 08/22] drm/amd/display: Allow tuning DCN314 bounding box

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

[Why]
We're missing the helpers from dcn20 that would allow
overriding these with DC debug options.

[How]
Use dcn20_patch_bounding_box to support overriding all the
relevant values.
