powerpc/5200: Fix size to request_mem_region() call
The Bestcomm driver requests a memory region larger than the one described in the device tree. This is due to an extra undocumented field in the bestcomm register structure. This hasn't been a problem up to now, but there is a patch pending to make the DT platform_bus support code use platform_device_add() which tightens the rules and provides extra checks for drivers to stay within the specified register regions. Alternately, I could have removed the extra field from the structure, but I'm not sure if it is still needed for resume to work. Better be safe and leave it in.
