drm/amd/display: Fixing hubp programming of 3dlut fast load

Browse Source 
[why]
HUBP needs to know the size of the lut's destination in MPC.
This is currently defaulted to 17, and needs to be set for specific
lut size.

[how]
Define and apply the missing hubp field. Taking this opportunity
to consolidate the programming of 3dlut into a hubp and mpc function.
