include: linux: Update Linux headers to v5.12-rc1

Browse source 
Update Linux headers to v5.12-rc1, to provide the
MEDIA_ENT_F_PROC_VIDEO_ISP entity function.

The DRM FourCC and modifiers that were manually added in commits
9db0ed5e20, 38f2efb05c and 90c793c698 are kept. New Intel DRM
format modifiers are conflicting with IPU3_FORMAT_MOD_PACKED, which is
updated as a result.

The V4L2 controls and formats that were manually added in commit
43d81d43fe are kept. This causes a conflict in the V4L2 control base
for V4L2_CID_USER_BCM2835_ISP_BASE that needs to be resolved in the
downstream Raspberry Pi kernel first.

The intel-ipu3.h header is manually exported with the
scripts/headers_install.sh script. The script complained about a missing
"WITH Linux-syscall-note" license extension, which has been worked
around manually. The issue has been reported upstream in [1].
