alpha/PCI: Use BAR index in sysfs attr->private instead of resource pointer

Currently, Alpha's pci_create_one_attr() stores a resource pointer in
attr->private, and pci_mmap_resource() loops through all BARs to find
the matching index.

Store the BAR index directly in attr->private and retrieve the resource via
pci_resource_n().  This eliminates the loop and aligns with the convention
used by the generic PCI sysfs code.

The PCI core change was first added in the commit dca40b186b75 ("PCI: Use
BAR index in sysfs attr->private instead of resource pointer").
