The White Hawk Single board is a single-board integration of the Renesas
White Hawk CPU and Breakout board stack, based on the R-Car V4H ES2.0
(R8A779G2) SoC.

For now, the only visible differences compared to the board stack are:
  - The SoC is an updated version of R-Car V4H (R8A779G0),
  - The serial console uses an FT2232H instead of a CP2102 USB-UART
    bridge, with CTS/RTS wired.

v2:
  - Add Reviewed-by,
  - Refer to hscif0_pins directly,
  - Add SoC name to top-level comment.
