Introduce new eth_receive routine
The purpose of this routine is receiving a single network frame, outside of
U-Boot's NetLoop(). Exporting it to standalone programs that run on top of
U-Boot will let them utilise networking facilities. For sending a raw frame
the already existing eth_send() can be used.
The direct consumer of this routine is the newly introduced API layer for
external applications (enabled with CONFIG_API).
