ARM: 7774/1: Fix dtb dependency to use order-only prerequisites
The %.dtb dependency is specified to depend on the PHONY "scripts". That means that it'll build every time even if the underlying dtb file hasn't been touched. Use an order-only prerequisites to fix this. Also mark "dtbs" as PHONY for correctness. This was broken in (70b0476 ARM: 7513/1: Make sure dtc is built before running it).
