As for several other exynos devices we need to disable the video4linux's udev rule OR disable FIMC IS and patch kernel to fix build error without FIMC IS. Add dependency on postmarketos-base-downstream-disable-udev-v4l to override the v4l rule with symlink to /dev/null. We can then drop FIMC IS patch and keep kernel config more similar to original one.
