[U-Boot] [PATCH 7/8] dts/Makefile: don't use cpp -P

[Stephen Warren]

From: Stephen Warren <swarren at nvidia.com>

Recent dtc supports #line directives in the input source code, and even
uses them to generate useful line numbers in any messages it emits. Stop
passing -P to cpp, since there's no need any more.
