PCI: Move Open Firmware devspec attribute to PCI common code 

Move the devspec OF attribute to PCI common code's set of device attributes
since it's not architecture dependent.  As a side effect microblaze and
powerpc no longer need to use pcibios_add_platform_entries().

[bhelgaas: fold in #include for compile error]
