media: rockchip: rkisp1: destage Rockchip ISP1 driver

All the items in the TODO list were addressed, uapi was reviewed,
documentation written, checkpatch errors fixed, several bugs fixed.

There is no big reason to keep this driver in staging, so move it out.

Dt-bindings Verified with:
make ARCH=arm64 dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/media/rockchip-isp1.yaml

-* streaming paths (mainpath and selfpath) check if the other path is streaming
-in several places of the code, review this, specially that it doesn't seem it
-supports streaming from both paths at the same time.
-
-NOTES:
-* All v4l2-compliance test must pass.
-* Stats and params can be tested with libcamera and ChromiumOS stack.
