[SCSI] bfa: driver compatibility with 32bit libs
Replaced usage of void * with u64 in data structure shared between
brocade user space libraries and the bfa driver to address pointer
size changes across 32-bit vs 64-bit to have the compatibility between
32bit library and 64bit driver and vice versa.
