This is wrong, but needed in order to avoid overlapping ranges with the OTP area added in the next commit. A refactor of this part of the device tree is needed: according to Wiibrew[1], this area starts at 0x0d800000 and spans 0x400 bytes (that is, 0x100 32-bit registers), encompassing PIC and GPIO registers, amongst the ones already exposed in this device tree, which should become children of the control@d800000 node.
