| usb: xhci: Add missing endian conversions (cpu_to_leXX / leXX_to_cpu)
|
| 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.

This introduces no functional change for existing platforms as the
barebox xHCI driver doesn't run on any big-endian CPUs.
