Subject: [PATCH] soc: litex: Properly depend on HAS_IOMEM

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 not 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.

Fixes: 22447a99c97e ("drivers/soc/litex: add LiteX SoC Controller driver")
