With the exceptions of ds109, ds414, icnova-a20-swac, nokia_rx51 and stemmy, disable ATAG support. A large number of platforms had enabled support but never supported a kernel so old as to require it. Further, some platforms are old enough to support both, but are well supported by devicetree booting, and have been for a number of years. This is because some of the ATAGs related functions have been re-used to provide the same kind of information, but for devicetree or just generally to inform the user. When needed still, rename these functions to get_board_revision() instead, to avoid conflicts. In other cases, these functions were simply unused, so drop them.
