Blackfin: bf518f-ezbrd: fix dsa resources
On bf518-ezbrd with DSA Ethernet switch enabled, on chip MAC is connecting to phy at address 3. If allowing the netdevice framework to probe both 3 phys of the switch when registering MAC phy, phy at address 1 is checked for link active status other than phy at address 3. If connecting a cable to port 2 and leave port 1 open, link status in phy 2 and 3 are online, while that in phy 1 is offline. So, the phy layer sets wrong offline status to net device on port 3. In this case, no data can be transferred via ethernet port 2. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
