arm64: dts: renesas: gray-hawk-single: Add second debug serial port
Describe the second debug serial port (CN9800) on the Gray Hawk Single
board, as provided by HSCIF2, including the SCIF_CLK2 external clock
source, and all related pin control.
Based on a patch for Gray Hawk in the BSP by Nghia Nguyen.
