The `dio200_read8()`, `dio200_write8()`, `dio200_read32()` and `dio200_write32()` functions apply a right-shift to the register offset for some devices and then perform the actual register access. Factor the register access part out to new functions `dio200___read8()`, `dio200___write8()`, `dio200___read32()`, and `dio200___write32()`. This will reduce duplicated code in a subsequent patch that will conditionally compile support for port I/O as part of the `HAS_IOPORT` changes.
