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 commits9db0ed5e20,38f2efb05cand90c793c698are 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 commit43d81d43feare 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].
