Unlike other build products in the Linux kernel, there is no 'make
*install' mechanism to put devicetree blobs in a standard place.

This patch is an attempt to fix this problem.  Akin to 'make install',
this creates a new make target, dtbs_install.  The script that gets
called defers to a distribution or user supplied installdtbs binary,
if found in the system.  Otherwise, the default action is to install the
built dtbs into

  /lib/devicetrees/${kernel_version}/${dts_filename}.dtb

This is done to keep dtbs from different kernel versions separate until
things have settled down.  Once the dtbs are stable, and not so strongly
linked to the kernel version, the devicetree files will most likely move
to their own repo.  Users will need to upgrade install scripts at that
time.

/lib has been selected over /boot since /boot is often a FAT filesystem
and a majority of the dts filenames are longer than 8+3.

Ok with the change to /lib in light of /boot partitions formatted to FAT

This script shouldn't be installing directly to the filesystem, but
rather some staging area that then gets copied to the desired location
by distro-/use-specific scripts. As such, the filesystem in /boot isn't
relevant.

Why do you think that?  All the other install targets install direct to
the common destinations unless you ask for an alternative location.  Why
should this be any different?
