[OpenBIOS] [PATCH] pci: only try and detect Mac driver in PCI ROM for PPC machines

[Mark Cave-Ayland]

It seems that the VGA option ROM isn't mapped on SPARC64 which causes
a fault upon access.

Temporarily handle this by surrounding the code in #ifdef CONFIG_PPC
guards until the proper solution can be implemented.
