dts: support building all dtb files for a specific vendor
This adjusts OF_UPSTREAM to behave more like the kernel by allowing for
all the devicetree files for a given vendor to be compiled. This is
useful for Qualcomm in particular as most boards are supported by a
single U-Boot build just provided with a different DT.
