[PATCH v1 1/4] usb: xhci: Add missing endian conversions (cpu_to_leXX / leXX_to_cpu)

[Stefan Roese]

While trying to use the U-Boot xHCI driver on the MIPS Octeon platform,
which is big endian, I noticed that the driver is missing a few endian
conversion calls. This patch adds these missing endian conversion
calls.
