From: Alexandru Ardelean <alexandru.ardelean@xxxxxxxxxx> commit be24c65e9fa2486bb8ec98d9f592bdcf04bedd88 upstream. The ADI AXI ADC driver requires IO mem access and OF to work. This change adds these dependencies to the Kconfig symbol of the driver. This was also found via the lkp bot, as the devm_platform_ioremap_resource() symbol was not found at link-time on the S390 architecture.
