net/fec: add dual fec support for mx28
This patch is to add mx28 dual fec support. Here are some key notes for mx28 fec controller. - The mx28 fec controller naming ENET-MAC is a different IP from FEC used on other i.mx variants. But they are basically compatible on software interface, so it's possible to share the same driver. - ENET-MAC design on mx28 made an improper assumption that it runs on a big-endian system. As the result, driver has to swap every frame going to and coming from the controller. - The external phys can only be configured by fec0, which means fec1 can not work independently and both phys need to be configured by mii_bus attached on fec0. - ENET-MAC reset will get mac address registers reset too. - ENET-MAC MII/RMII mode and 10M/100M speed are configured differently FEC. - ETHER_EN bit must be set to get ENET-MAC interrupt work.
