arm64: dts: qcom: sc8280xp: Use MMCX for all DP controllers
While MDSS_GDSC is a subdomain of MMCX, Linux does not respect this relationship and sometimes invokes sync_state on the rpmhpd (MMCX) before the DisplayPort controller has had a chance to probe. The result when this happens is that the power is lost to the multimedia subsystem between the probe of msm_drv and the DisplayPort controller - which results in an irrecoverable state. While this is an implementation problem, this aligns the power domain setting of the one DP instance with that of all the others.
