[POWERPC] Don't try to allocate resources for a Freescale POWERPC PHB
The Freescale PCI PHBs actual report back values in the BAR registers
this causes issues in that we try to allocate resources for them
and will get error messages like the following on MPC8544 DS:
PCI: Failed to allocate mem resource #1:[EMAIL PROTECTED] for 0000:00:00.0
To address this if we are class PCI_CLASS_PROCESSOR_POWERPC, a normal
header type, and the PHB we clear out all the resources.
