drm/msm/sde: remove vote on power handle disable

sde driver allows to vote through display rsc and
apps rsc. It also allows to switch between these
two rsc dynamically. However, ebi/mnoc ab/ib votes
were not removed when apps rsc was used as a main
voter client. This patch remove the vote on
disable path and update the display rsc state
properly to take correct path.
