binman: Automatically include a U-Boot .dtsi file
For boards that need U-Boot-specific additions to the device tree, it is
a minor annoyance to have to add these each time the tree is synced with
upstream.
Add a means to include a file (e.g. u-boot.dtsi) automatically into the .dts
file before it is compiled.
The file uses is the first one that exists in this list:
arch/<arch>/dts/<board.dts>-u-boot.dtsi
arch/<arch>/dts/<soc>-u-boot.dtsi
arch/<arch>/dts/<cpu>-u-boot.dtsi
arch/<arch>/dts/<vendor>-u-boot.dtsi
arch/<arch>/dts/u-boot.dtsi
