dt-bindings: arm: altera: document the Agilex7-M devkit

The Agilex7-M is a rebranded version of the original Agilex SoC. The
Agilex7-M SoC has the same core peripherals as the Agilex device.

This change is to document the Agilex7m devkit which has the Agilex7-M
device. The Agilex7-M SoC supports DDR4, DDR5, LPDDR5, PCIE 5.0(x16), but
not QSPI.

Also, now that Altera has separated from Intel, use the "altr" company
prefix.
