Jayachandran C. d5d4261f35 Update memory and resource allocation code for SoC devices
The XLP on-chip devices have PCI configuration headers, but some of the
devices need custom resource allocation code.
- devices with no MEM/IO BARs with registers in PCIe extended reg
  space have to be handled in memory resource allocation
- devices without INTPIN/INTLINE in PCI header can be supported
  by having these faked with a shadow register.
- Some devices does not allow 8/16 bit access to the register space,
  he default bus space cannot be used for these.

Subclass pci and override attach and resource allocation methods to
take care of this.

Remove earlier code which did this partially.
