[ 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.
