Subject: [PATCH v2 6/8] DT: arm: Add Renesas RZ/N1 SoC base device tree file

This adds the Renesas RZ/N1 Family (Part #R9A06G0xx) SoC
bare bone support.

This currently only handles generic parts (gic, architected timer)
and a UART.
For simplicity sake, this also relies on the bootloader to set the
pinctrl and clocks.
