Replace little-endian-only constants in ohci.h with cpu-native
constants, so that they can be converted to little-endian or big-endian

ey take on the beXX forms when only big-endian controllers

A bit in the flags field of struct ohci_hcd, OHCI_BIG_ENDIAN,
enables the the transformed functions to support both big-endian
