Add the Rockchip ISP1 specific processing parameter format
V4L2_META_FMT_RK_ISP1_PARAMS and metadata format
V4L2_META_FMT_RK_ISP1_STAT_3A for 3A.

Hello,

This patch is a continuation of:

https://patchwork.kernel.org/project/linux-arm-kernel/patch/20191106120132.6876-2-helen.koike@collabora.com/

These formats are already documented under
Documentation/userspace-api/media/v4l/pixfmt-meta-rkisp1.rst

We had agreed to keep under
drivers/staging/media/rkisp1/uapi/rkisp1-config.h while the driver was
in staging, since we are moving it out of staging, I guess this is the
time :)

Regards,
Helen

Use 'Params' and 'Statistics' to conform to the other descriptions.

Drive-by observation: "parameters" is the exact same length as 
"statistics". I could understand abbreviating both, or neither, but the 
mix just looks decidedly odd.
