And replace many references of ${ROOT_DIR}/common with
${ROOT_DIR}/${KERNEL_DIR}, which makes it a lot easier
to branch off of ACK and update the KERNEL_DIR.
The variable of KERNEL_DIR will be set in build/_setup_env.sh
to the directory of the build config file by default if it's
not set explicitly in the build config file or in environment.
Test: build test with following configs
common/build.config.gki.aarch64
common/build.config.db845c

To create boot images for multiple kernels for CI testing, we
need the initramfs image.

Previously the db845c build was cat'ng the db845c_gki.fragment
with the gki_defconfig. The correct way to merge fragments is to use
the merge_configs script.

The default goals for an ARCH=arm64 kernel will build all of the dtb
files available in the tree, and hard-codes the generation of a
gzip-compressed Image artifact. For GKI, we want to support various
compression methods (gz, lz4 and uncompressed) and this can be handled
outside of kbuild where compressor flags can be tuned. Also, GKI does
not need to build any dtb files because it is board-neutral, and in most
cases the dtbs will come from downstream kernels, not ACK.
On arm and aarch64, this suppresses the generation of the useless gzip
compressed Image artifact, and dtbs on the gki configs, which do not make
sense. The x86 defaults were already optimal but make them match
aarch64. On db845c, this builds only the needed dtb file and a compressed
artifact for backwards compatibility.

Add a build config for db845c.
This one uses cat to merge the gki_defconfig with
the db845c_gki.fragment.
This isn't as ideal as using merge_config.sh which
provides more useful warnings but I couldn't manage
to get merge_config.sh to run properly within the
context of the PRE_DEFCONFIG_CMDS.
This does however result in a .config identical
to the merge_config result.
