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

Fields of MAINTAINERS file sorted according to output of
./scripts/parse-maintainers.pl --input=MAINTAINERS --output=MAINTAINERS
