[PATCH v6 4/6] ARM: dts: Renesas RZ/N1 SoC base device tree file

[Michel Pollet]

This adds the Renesas RZ/N1D (Part #R9A06G032) 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.
