Move this header out of the common header. Network support is used in quite a few places but it still does not warrant blanket inclusion. Note that this net.h header itself has quite a lot in it. It could be split into the driver-mode support, functions, structures, checksumming, etc. Signed-off-by: Simon Glass <sjg@chromium.org>
