if user disables IOC from debugger at startup (by clearing @ioc_enable), @ioc_exists is cleared too. This means boot prints don't capture the fact that IOC was present but disabled which could be misleading. So invert how we use @ioc_enable and @ioc_exists and make it more canonical. @ioc_exists represent whether hardware is present or not and stays same whether enabled or not. @ioc_enable is still user driven, but will be auto-disabled if IOC hardware is not present, i.e. if @ioc_exist=0. This is opposite to what we were doing before, but much clearer. This means @ioc_enable is now the "exported" toggle in rest of code such as dma mapping API.
