[U-Boot] [PATCH] fdt: fix dts preprocessor options

[Allen Martin]

Using "-ansi" preprocessor option will cause dts lines that begin with
'#' to choke the preprocessor.  Change to "-x assembler-with-cpp"
instead which is what the kernel uses to preprocess dts files.

Well, it's what the kernel hopefully /will/ use if I can ever get the
patch accepted. But anyway, this seems good to me.
