MIPS: RB532: Simplify dev3 init
As rb532_dev3_ctl_res is not used by any platform device, it can be dropped when not used for holding the physical address of the device 3 controller. Also a size of one byte should suffice when ioremapping the physical address mentioned above, as only a single byte is being read from and written to it.
