rtc: zynqmp: depend on HAS_IOMEM
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.
