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.
