drm/amd/display: fix MPO HUBP underflow with Scatter Gather
[why]
With Scatter Gather enabled, HUBP underflows during MPO enabled video
playback. hubp_init has a register write that fixes this problem, but
the register is cleared when HUBP gets power gated.
[how]
Make a call to hubp_init during enable_plane, so that the fix can
be applied after HUBP powers back on again.
