[PATCH 3/5] bfa: use pci_iomap() and pci_iounmap()

[PATCH 3/5] bfa: use pci_iomap() and pci_iounmap()

[Jing Huang]

Use pci_iomap() and pci_iounmap() to simplify the code. Remove uncessary #ifdef
check for ia64 (it was added as a workaound for some RHEL 5.x release which 
doesn't export iounmap function)
