arm64: dts: freescale: imx8mp-skov: operate SoC in nominal mode 



To reduce heat generation, the Skov i.MX8MP boards should run in nominal
drive mode with a VDD_SOC voltage of 850 mV.

At this operating point, not all frequencies that are achievable with
overdrive mode are possible, so import imx8mp-nominal.dtsi to clock down
the clocks.
