below is a patch that adds the dtbs_install target to arm64. Taken
from arm where this was already implemented.

Subject: [PATCH] arm64, dts: Add dtbs_install make target

This adds the dtbs_install make target to arm64. The target has been
introduced already to arch/arm with the following commit:

f4d4ffc03efc kbuild: dtbs_install: new make target

Implementation for arm64 is the same as for arm.

With 'dtbs_install' all config enabled dtb files are installed to
either the INSTALL_DTBS_PATH directory or the default location:

$INSTALL_PATH/dtbs/$KERNELRELEASE
