new `rocket` Rockchip NPU driver

[clee]

Any chance rkllama will support the new upstream NPU driver? https://dri.freedesktop.org/docs/drm/accel/rocket/index.html

I'm also looking forward to this :-)

After some research, I found another way for the NPUs as dri (not only rk3588) : build and submit cmd stream (by mesa teflon / user’s program) -> libdrm -> kernel driver -> npu hardware. You may see cmd stream by cat /sys/kernel/debug/dri/0/ring.
