[PATCH 4/8] alpha: initialize PCI sysfs bin attributes for lockdep

[Magnus Lindholm <linmag7@gmail.com>]

Alpha allocates PCI resource sysfs bin attributes dynamically.  When
lockdep is enabled, dynamically allocated sysfs attributes need their
lockdep metadata initialized before registration.

Call sysfs_bin_attr_init() before registering the resource bin attribute
with sysfs.  This avoids unrelated sysfs lock-class warnings once Alpha
enables lockdep support.
