There can be 1, 2 or 4 SoCs(nodes) in a multi-chip XLP board. Add an
option for multi-chip boards in case of XLP, and make the number of
nodes configurable.

Upto 4 Netlogic XLP SoCs can be connected over ICI links to form a
coherent multi-node system.  Each SoC has its own set of on-chip
devices including PIC.  To support this, add a per SoC stucture and
use it for the PIC and SYS block addresses instead of using global
variables.

The XLP USB controller appears as a device on the internal SoC PCIe
bus, the block has 2 EHCI blocks and 4 OHCI blocks. Change are to:

* Add files netlogic/xlp/usb-init.c and asm/netlogic/xlp-hal/usb.h
  to initialize the USB controller and define PCI fixups. The PCI
  fixups are to setup interrupts and DMA mask.
* Update include/asm/xlp-hal/{iomap.h,pic.h,xlp.h} to add interrupt
  mapping for EHCI/OHCI interrupts.

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.

Remove NETLOGIC_ prefix from gpio register definitions, this will
bring it in-line with the other Netlogic headers.

Having NETLOGIC prefix here is misleading because these are XLR/XLS

Create a common NMI and reset handler in smpboot.S and use this for
both XLR and XLP.  In the earlier code, the woken up CPUs would
busy wait until released, switch this to wakeup by NMI.

The initial wakeup code or XLR and XLP are differ since they are
started from different bootloaders (XLP from u-boot and XLR from
netlogic bootloader). But in both platforms the woken up CPUs wait
and are released by sending an NMI.

Add support for starting XLR and XLP in 1/2/4 threads per core.
