Commit37c8a5fafa("kbuild: consolidate Devicetree dtb build rules") moved the location of 'dtbs_install' target which caused dtbs to not be installed when building debian package with 'bindeb-pkg' target. Update the builddeb script to use the same logic that determines if there's a 'dtbs_install' target which is presence of the arch dts directory. Also, use CONFIG_OF_EARLY_FLATTREE instead of CONFIG_OF as that's a better indication of whether we are building dtbs. This commit will also have the side effect of installing dtbs on any arch that has dts files. Previously, it was dependent on whether the arch defined 'dtbs_install'.

# Simple script to generate a deb package for a Linux kernel. All the
|

# complexity of what to do with a kernel after it is installed or removed
|
|
# is left to other scripts and packages: they can install scripts in the
|
|
# /etc/kernel/{pre,post}{inst,rm}.d/ directories (or an alternative location
|
|
# specified in KDEB_HOOKDIR) that will be called on package install and
|
|
# removal.
