Subject: [PATCH] ARM: dts: qcom: keep VDD_MMCX and VDD_MXC supplies always on
 for Sun RUMI

Set regulator-always-on for VDD_MMCX and VDD_MXC on Sun
RUMI. This ensures that clock controller register values
are maintained since RUMI isn't simulating register
retention across VDD_MMCX or VDD_MXC power collapse.
