ARM: dts: nxp: imx7d-pico: add cpu-supply nodes
The PICO-IMX7D SoM has the usual power supply configuration using
output sw1a of PF3000 PMIC, which was defined in downstream derivative
of linux-imx (see link) in the sources for "Android Things" devkit.
It is required to support CPU frequency scaling.
Map the respective "cpu-supply" nodes of each core to sw1a of the PMIC.
Enabling them causes cpufreq-dt, and imx-thermal drivers to probe
successfully, and CPU frequency scaling to function.
