[ Upstream commit ddd0521549a975e6148732d6ca6b89ffa862c0e5 ]
The Xilinx zynqmp RTC 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: 09ef18bcd5ac ("rtc: use devm_platform_ioremap_resource() to simplify
code")

If you say yes here you get support for the RTC controller found on
Xilinx Zynq Ultrascale+ MPSoC.
