arm64: dts: renesas: Add support for solidrun rzg2ul som on hb-ripple

Add support for the SolidRun RZ/G2UL SoM [1] on HummingBoard Ripple [2].

The SoM features:
  - 100Mbps Ethernet with PHY
  - eMMC
  - 512MB/1GB DDR
  - WiFi + Bluetooth
  - SDHI Mux switching between eMMC and Carrier Board

The HummingBoard Ripple is a reduced version of HummingBoard Pulse,
featuring:
  - 2x USB-2.0 Type-A connector
  - 1x 100Mbps RJ45 Ethernet
  - micro-HDMI connector (not usable with RZ/G2UL SoM)
  - microSD connector
  - mini-PCI-E connector with SIM slot supporting USB-2.0 interface
  - MIPI-CSI Camera Connector (not described without specific camera)
  - RTC with backup battery

The carrier board is identical between RZ/G2L, RZ/G2LC, RZ/G2UL and
RZ/V2L SoMs, yet only the RZ/G2LC combination has a product page [2].

RZ/G2UL SoM shares SCIF2 pins between on-SoM Bluetooth and carrier
board.  Provide dt overlay changing pin function from uart to GPIO LED
control.

While the variant being supported here is named "Ripple", the overlay
still carries the "pulse" suffix as it would fit all its variants.

Descriptions for eMMC and microSD are shared with G2L SoM and
HummingBoard IIoT.
