[U-Boot] [PATCH V2 REPOST 0/9] rely on latest dtc, simplify

[Stephen Warren]

This is a series of patches which simplifies the rules to build *.dts in
U-Boot by relying on features in the latest dtc. The include rules are
made more consistent between cpp (when processing *.dts) and dtc. The cpp
flags are made more consistent with the way the kernel processes *.dts to
allow better portability of *.dts between the two.

I'm sending V2 now that dtc-1.4.0 has been tagged/released, and hence
there's a version number that patch 1/9 "Validate dtc is new enough" can
check for. I'll leave it up to you whether this series is applicable for
the current or next release.

This repost of V2 also picks up various Acked-by's that I've received
