net: fec: avoid BD pointer type cast to 32bit

Browse Source 
In aarch64 system, the BD pointer is 64bit, and the high-order 32-bits
of the address is effective, so replace usigned with (void *) type to
aovid 64bit address is casted to 32bit in .fec_enet_get_nextdesc() and
.fec_enet_get_prevdesc() functions.
