This series adds support for CTCISZ Ninenine Pi, which ships an Loongson
2K0300 SoC and various peripherals. The vendor prefix and the board are
documented and basic SoC/board devicetrees are added.

I've successfully booted into console with vendor U-Boot, a bootlog
could be obtained here[1]. DTB and initramfs must be built into the
kernel as the vendor bootloader cannot pass them and upstream U-Boot
support for LoongArch is still WIP.

Thanks for your time and review.

I'm sorry. As there is no consensus yet on the name
of the development board, could you please refrain
from picking my R_B until this discussion is completed?
Thank you so much for your understanding and cooperation!
