Subject: [PATCH] kbuild: rpm-pkg: Add dtbs support

From: Janne Grunau <j@...nau.net>

Based on the dtbs support in builddeb. Both Fedora and openSUSE kernel
rpm install their dtbs in "/boot/dtb-${KERNELRELEASE}". There seems no
other popular rpm based distributions which would benefit from dtbs
support and are not derived from those two.
