net/designware: add error message on DMA reset timeout
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.
