[TG3]: Fix performance regression on 5705.
A performance regression was introduced by the following commit: commit ee6a99b5 Author: Michael Chan <mchan@broadcom.com> Date: Wed Jul 18 21:49:10 2007 -0700 [TG3]: Fix msi issue with kexec/kdump. In making that change, the PCI latency timer and cache line size registers were not restored after chip reset. On the 5705, the latency timer gets reset to 0 during chip reset and this causes very poor performance. Update version to 3.84.
