dts, kbuild: Implement support for dtb vendor subdirs
This patch adds support of vendor sub directories for dtb files. Subdirectories can be specified in $(dts-dirs). Kbuild traverses over all directories while building and installing dtb files. The directory tree is also reflected in the install path. Tested-by: Andrew Bresticker <abrestic@chromium.org> Signed-off-by: Robert Richter <rrichter@cavium.com> (cherry picked from commit 323a028d39cd8df37b1c6a62ac04987647ae4b67) Signed-off-by: Kevin Hilman <khilman@linaro.org>
