More fully initialize cardbus bridges. We now call the new generic
cardbus bridge init routine for all cardbuses. This routine attempts to compensate for BIOSes that do not setup the cardbus bridge into legacy mode. Since this is becoming more common, and cardbus pci cards have appeared on the market, this makes sense. Do some TI113x specific initialization. This came in as part of the patch. Report TI1[1234]XX specific config registers protected by bootverbose. Minor code cleanup while I'm here. I've also removed the unused code present in the original patches, and cleaned it up slightly in places as well. The original patches supported more than one card, but these patches support just one. We should likely revisit this in the future. This makes the Compaq card that Walnut Creek CD purchased for me work in my bouncer box. This is a MFC candidate. However, I'd like to get some airtime on these patches on as many laptops as possible before doing the MFC. It does change things somewhat. In theory, apart from the minor TI tweaks, this shouldn't change anything if the bridge is in legacy mode already. Submitted by: sanpei@sanpei.org (MIHIRA Yoshiro)
