drm/amd/display: Make dc_state_update const in commit path

Browse source

[Why]
The state-update commit path only reads the caller's update
descriptor, it never mutates the dc_state_update root. Making the
pointer const documents that contract.

[How]
Add const to the updates parameter of dc_update_state and
dc_check_state_update. Mark the single-assignment locals in
dc_update_state_init const and replace the memset plus
field-by-field assignment with a compound literal initializer.
