bnx2x: Force fundamental reset for EEH recovery 

commit da29370056 upstream.

EEH recovery for bnx2x based adapters is not reliable on all Power
systems using the default hot reset, which can result in an
unrecoverable EEH error. Forcing the use of fundamental reset
during EEH recovery fixes this.
