Subject: [PATCH 6/6] ARM: i.MX6 Phytec PFLA02: Add supplies for the SoC internal regulators

The SoC internal regulators for the CPU and the SoC come from the
DA9063 vdd_core and vdd_soc. Add this relationship to the device tree
so that the voltage drop on the SoC internal LDO regulators can be
minimized.
