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.
