You may have a look at the source code of the failed assert.

You probably don't have a Micrel PHY or the wrong model. The Altera 
Cyclone V support pre-dates the FDT support. It would be good to add the 
FDT support to this BSP and the corresponding libbsd drivers. You can 
try to use the generic PHY driver, e.g. replace

RTEMS_BSD_DRIVER_MIPHY;

with

SYSINIT_DRIVER_REFERENCE(ukphy, miibus);
