Subject: [PATCH v2 4/6] arm64: dts: qcom: sm8450: Additionally manage MXC
 power domain in camcc

From: Jagadeesh Kona <quic_jkona@...cinc.com>

Camcc requires both MMCX and MXC rails to be powered ON to configure
the camera PLLs on SM8450 platform. Hence add MXC power domain to
camcc node on SM8450.
