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.

This is not enough it should be

ARCH_ZYNQ || ARCH_ZYNQMP || ARCH_VERSAL || ARCH_VERSAL_NET
