[U-Boot] [PATCH 1/2] kbuild: make arch-dtbs target PHONY

[Stephen Warren]

From: Stephen Warren <swarren at nvidia.com>

Without this, the arch-dtbs target only gets evaluated when building
U-Boot the first time, not when re-building (incrementally building)
U-Boot. Thus incremental builds ignore changes to DTB files.
