arm64: dts: renesas: Introduce r8a774a1-beacon-rzg2m-kit

Beacon EmebeddedWorks, formerly Logic PD is introducing a new
SOM and development kit based on the RZ/G2M SoC from Renesas.

The SOM supports eMMC, WiFi and Bluetooth, along with a Cat-M1
cellular radio.

The Baseboard has Ethernet, USB, HDMI, stereo audio in and out,
along with a variety of push buttons and LED's, and support for
a parallel RGB and an LVDS display.
