smsc95xx: mark link down on startup and let PHY interrupt deal with carrier changes

commit 07d69d4238418746a7b85c5d05ec17c658a2a390 upstream.

Without this patch sysfs reports the cable as present

flag@flag-desktop:~$ cat /sys/class/net/eth0/carrier
1

while it's not:

flag@flag-desktop:~$ sudo mii-tool eth0
eth0: no link

Tested on my Beagle XM.

v2: added mantainer to the list of recipient
