If for some reason DMA module fails to reset user oserves only this:
--->---
# dhcp
Trying dwmac.e0018000
FAIL
--->---
This message makes not much sense.
With proposed change error message will be more helpful:
--->---
# dhcp
Trying dwmac.e0018000
DMA reset timeout
FAIL
--->---
For example user may do power toggle to recover board functionality.
