Subject: [PATCH 3/6] Add config option to fix bootloader cmdline args
Android bootloader passes some arguments in kernel command
line, that make booting custom OSes harder:
* skip_initramfs
* root=PARTUUID=...
* init=/init
Those parameters override default boot partition to hardcoded,
set init binary to /init, disable booting from initramfs.
If enabled, those parameters will be erased from bootloader's
command line, and custom OS can boot the way it likes.

Arm64 has generated headers that other arches don't, didn't investigate why this
is able to compile in downstream (our upstream). Possibly due to out-of-tree build.
Note the hacky relative include. May not work in more complicated setups.
