Subject: [PATCH 5.11 093/120] iio: adc: adi-axi-adc: add proper Kconfig dependencies

From: Alexandru Ardelean <alexandru.ardelean@...log.com>

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.
