The regmap API has an endianness setting for formatting reads and writes. This can be set by the usual DT "little-endian" and "big-endian" properties. To work properly the associated regmap_bus needs to read/write in native endian. The "syscon" DT device binding creates an mmio-based regmap_bus which performs all reads/writes as little-endian. These values are then converted again by regmap, which means that all of the MIPS BCM boards (which are big-endian) have been declared as "little-endian" to get regmap to convert them back to big-endian. Modify regmap-mmio to use the native-endian functions __raw_read*() and __raw_write*() instead of the little-endian functions read*() and write*(). Modify the big-endian MIPS BCM boards to use what will now be the correct endianness instead of pretending that the devices are little-endian.
