[PATCH v2 3/6] arm64: dts: imx8mp: add fsl,nominal-mode property into nominal.dtsi

The imx8mp-nominal.dtsi is meant to be included into boards that want to
override the default overdrive clock settings with settings suitable for
running in nominal drive mode at its lower required voltage.

Specifying fsl,nominal-mode informs drivers of this fact, so they can
sanity check runtime clock reconfiguration to observe the limits imposed
by nominal mode.
