USB: Implement support for "split" endian OHCI
This patch separates support for big endian MMIO register access and big endian descriptors in order to support the Toshiba SCC implementation which has big endian registers but little endian in-memory descriptors. It simplifies the access functions a bit in ohci.h while at it.
