Remove unused OPI_BOOT_OUT staging directory. Boot.img is now
just the U-Boot binary for build system packaging. The actual
FAT32 boot partition with kernel/DTB/ramdisk is created by
mkimg_gpt.sh, which runs outside the build system and has
access to mkfs.vfat and mcopy.

mkfs.fat and mcopy are disallowed in Android 16 build system.
Use pre-built U-Boot binary as boot.img for packaging purposes.
The actual bootable image is created by mkimg_gpt.sh.

Without explicit definition, the variable is empty when
TARGET_NO_KERNEL was set. Define it to ensure boot.img
is created for the target-files packaging step.

The kernel repo only has the Orange Pi 5 Ultra DTB. Remove
references to other OPI5 variant DTBs. Fix ramdisk dependency
to use built ramdisk.img directly.
