Subject: [PATCH] ip2: use newer pci_get functions

This is one of a series of patches I plan to gradually trickle into the
tree which eliminates almost all remaining use of pci_find_* and lets me
build a pci_find_* free kernel for all but some obscure ISDN and SCSI
drivers. This is important as all pci_find_* users are not hotplug safe
- even if they are not the device being plugged.
