Subject: [PATCH 1/5] dt-bindings: clock: qcom,sm8450-videocc: Add MXC power
 domain

To configure the video PLLs and enable the video GDSCs on SM8450,
SM8475, SM8550 and SM8650 platforms, the MXC rail must be ON along
with MMCX. Therefore, update the videocc bindings to include
the MXC power domain on these platforms.

Fixes: 1e910b2ba0ed ("dt-bindings: clock: qcom: Add SM8450 video clock controller")
