drm/amd/display: Add hubp_init entry to hubp vtable

Browse source

Different HW will need to init HUBP differently. For now, add a vtable
entry, and hook a NO-OP for DCN1 and DCN2.

In addition, future HW will need to access the HUBPREQ_DEBUG and
CUR_TTU_CNTL0 register for hubp_init. Add that here.
