e1000e: 82566DC fails to get link 

Two recent patches to cleanup the reset[1] and initial PHY configuration[2]
code paths for ICH/PCH devices inadvertently left out a 10msec delay and
device ID check respectively which are necessary for the 82566DC (device id
0x104b) to be configured properly, otherwise it will not get link.
