Add board code and DTs for Renesas RZ/A1 SoC-based GR-Peach, which is a cheap development platform with RZ/A1H SoC. The DTs are imported from Linux 5.0.11, commit d5a2675b207d . Currently supported are UART, ethernet and RPC SPI. The board can be booted from RPC SPI by writing the u-boot.bin binary to the beginning of the SPI NOR, e.g. using the "sf" command. The board can also be booted via JTAG by setting text base to 0x20020000, loading u-boot.bin there via JTAG and executing it from that address.
