ARM: dts: msm: enable display rsc for sm8150

Enable display rsc on sm8150 target for clock gating
and bw update. This hardware blocks has additional clocks
requirement for mode2 entry and exit sequences due to
VBIF fetch halt support. It also redirect all active
BW vote through display rsc instead of apps rsc. That
allows single node creation on apps rsc to reduce the
bus vote latency.
