The LiteX SOC controller driver makes use of IOMEM functions like
devm_platform_ioremap_resource(), which are only available if
CONFIG_HAS_IOMEM is defined.
This causes the driver to be enable under make ARCH=um allyesconfig,
even though it won't build.
By adding a dependency on HAS_IOMEM, the driver will not be enabled on
architectures which don't support it.

This option enables the SoC Controller Driver which verifies

LiteX CSR access and provides common litex_get_reg/litex_set_reg

All drivers that use functions from litex.h must depend on
