Landon J. Fuller a1df0d9592 Fix minor locking issues in the Power Mac Uninorth PCI bridge driver. 
- Call resource_int_value() once during attach, rather than within the
  pci_(read|write)_config() code path; this avoids taking a blocking mutex
  to read kenv variables.

- Use a spin lock to protect non-atomic config space accesses; this matches
  the behavior of Darwin's AppleMacRiscPCI driver.
