new at91_emac network driver (NET_MULTI api)
* add's at91_emac (AT91RM9200) network driver (NET_MULTI api) * enable driver with CONFIG_DRIVER_AT91EMAC * generic PHY initialization * modify AT91RM9200 boards to use NET_MULTI driver * the drivers has been tested with LXT971 Phy and DM9161 Phy at MII and RMII interface Signed-off-by: Jens Scharsig <js_at_ng@scharsoft.de> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>
