fdt: avoid bad MAKEALL status
Current versions of dtc always print a message like DTC: dts->dtb on file "dt.dtb.tmp" which cannot even be suppressed with "-qqq". To avoid incorrect MAKEALL status, we manually filter out this message. This is a bit complicated, as we have to make sure to set a correct return code. Also, get rid of the temp file: dtc accepts "-" for stdin. Signed-off-by: Wolfgang Denk <wd@denx.de> Cc: Simon Glass <sjg@chromium.org> Acked-by: Simon Glass <sjg@chromium.org>
