[PATCH] arm64: dts: fsl: imx8mq-evk: link regulator to VPU domain

From: Adam Ford <hidden>
Date: 2021-12-05 21:02:01

The SW1C regulator powers the VPU and the state isn't guaranteed
to always be on.  Link the VPU power-domain to the regulator to
ensure it is turned on before using the power domain.
