arm64: dts: socfpga: agilex7m: Add SoCFPGA Agilex7-M devkit

Browse Source 
The Agilex7-M devkit contains an Agilex7M SoC, which is a newly branded
version of the original Agilex SoC. The Agilex7M core peripherals are
identical to the Agilex SoC.

We can re-use the socfpga_agilex.dtsi for this devkit. The Agilex7-M
devkit supports PCIE 5.0(x16), DDR4, DDR5, LPDDR5 and does not have QSPI.
