MIPS: Netlogic: Add support for USB on XLP2xx
Add USB intialization code to handle the new XLP2XX USB 3.0 block.
This adds xlp/usb-init-xlp2.c to initialize the XLP2XX USB glue-logic
for XHCI and EHCI. Interrupt and IO offset code in xlp-hal/iomap.h
and xlp/nlm_hal.c is also updated for the new USB block.
