[TG3]: Fix performance regression on 5705.

A performance regression was introduced by the following commit:

    commit ee6a99b5

    [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.
