arm64: dts: qcom: sc8180x: Move DisplayPort for MMCX
The DisplayPort blocks are powered by MMCX and should be described as
such to ensure that power votes are done on the right resource.
This also solves the problem that sync_state is unaware of the DP
controllers needing MMCX to be kept alive during boot. As such this
change also fixes occasionally seen crashes during boot due to
undervoltage of MMCX.
