drm/amd/display: Add allow_clock_gating to dcn42 dccg

Browse Source 
[Why]
The allow_clock_gating function is present in all other DCN versions
and is required to properly migrate DCCG registers access from hwseq
to the dccg component, resolving register conflicts.

[How]
Add the missing .allow_clock_gating function pointer to the
dccg42_funcs struct.
