7b53eb4d40 MIPS: PCI: Multi-node PCI support for Netlogic XLP 
On a multi-chip XLP board, each node can have 4 PCIe links. Update
XLP PCI code to initialize PCIe on all the nodes.

8cd3d64c57 MIPS: PCI: Prevent hang on XLP reg read 
Reading PCI extended register at 0x255 on a bridge will hang if there
is no device connected on the link. Make PCI read routine skip this
register.

a264b5e8dc MIPS: PCI: Byteswap not needed in little-endian mode 
Rename function xlp_enable_pci_bswap() to xlp_config_pci_bswap(), which
is a better description for its functionality.  When compiled in
big-endian mode, xlp_config_pci_bswap() will configure the PCIe links
to byteswap.  In little-endian mode, no swap configuration is needed
for the PCIe controller, and the function is empty.

7034228792 MIPS: Whitespace cleanup. 
Having received another series of whitespace patches I decided to do this
once and for all rather than dealing with this kind of patches trickling
in forever.

9bac624b0f MIPS: Netlogic: XLP PCIe controller support. 
Adds support for the XLP on-chip PCIe controller. On XLP, the
on-chip devices(including the 4 PCIe links) appear in the PCIe
configuration space of the XLP as PCI devices.

The changes are to initialize and register the PCIe controller,
enable hardware byte swap in the PCIe IO and MEM space, and to
enable PCIe interrupts.
