Revert "of: use platform_device_add"
This reverts commit aac73f34542bc7ae4317928d2eabfeb21d247323. That commit causes two kinds of breakage; it breaks registration of AMBA devices when one of the parent nodes already contains overlapping resource regions, and it breaks calls to request_region() by device drivers in certain conditions where there are overlapping memory regions. Both of these problems can probably be fixed, but it is better to back out the commit and get a proper fix designed before trying again. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
