firewire: ohci: fix TI TSB82AA2 regression since 2.6.35
Revert commit 54672386ccf36ffa21d1de8e75624af83f9b0eeb
"firewire: ohci: fix up configuration of TI chips".
It caused massive slow-down and data corruption with a TSB82AA2 based
StarTech EC1394B2 ExpressCard and FireWire 800 harddisks.

http://thread.gmane.org/gmane.linux.kernel.firewire.user/4013
The fact that some card EEPROMs do not program these enhancements may be
related to TSB81BA3 phy chip errata, if not to bugs of TSB82AA2 itself.
We could re-add these configuration steps, but only conditional on a
whitelist of cards on which these enhancements bring a proven positive
effect.
