Beacon EmebeddedWorks is introducing a new kit based on the
RZ/G2N 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.  It uses the same baseboard
and SOM as the RZ/G2M.

This SOM has only 2GB of DDR, and beacon-renesom-som.dtsi contains
the base memory node, so an additional memory node isn't necessary.

V2:  Add missing du node entries.

Thanks for the update!

i.e. will queue in renesas-devel for v5.12.

BTW, r8a774[abe]1.dtsi define CPG_AUDIO_CLK_I. If you would use
that instead of R8A774[ABE]1_CLK_S0D4, all rcar_sound clocks
properties overrides would become identical, and you could consolidate
them back in beacon-renesom-baseboard.dtsi.

That can be done in a single patch on top later, though.
