Subject: [PATCH 5/6] arm64: dts: qcom: sm8550: Additionally manage MXC
 power domain in camcc

From: Vladimir Zapolskiy <vladimir.zapolskiy@...aro.org>

Camcc requires both MMCX and MXC rails to be powered ON to configure
the camera PLLs on SM8550 platform. Hence add MXC power domain to
camcc node on SM8550. While at it, update SM8550_MMCX macro to RPMHPD_MMCX
to align towards common macros.
