arm64: dts: qcom: sm8150: make dispcc cast minimal vote on MMCX
[ Upstream commit 617de4ce7b1c4b41c1316e493d4717cd2f208def ]
Add required-opps property to the display clock controller. This makes
it cast minimal vote on the MMCX lane and prevents further 'clock stuck'
errors when enabling the display.
