arm64: dts: freescale: Add basic dtsi for imx943

Add the minimal dtsi support for i.MX943. i.MX943 is the first SoC of
i.MX94 Family, create a common dtsi for the whole i.MX94 family, and the
specific dtsi part for i.MX943.

The clock, power domain and perf index need to be used by the device nodes
for resource reference, add them along with the dtsi support.
