Subject: [PATCH] clk: staging: Specify IOMEM dependency for Xilinx Clocking
 Wizard driver

The Xilinx Clocking Wizard driver uses the devm_ioremap_resource
function, but does not specify a dependency on IOMEM in Kconfig. This
causes a build failure on architectures without IOMEM, for example, UML
(notably with make allyesconfig).

Fix this by making CONFIG_COMMON_CLK_XLNX_CLKWZRD depend on CONFIG_IOMEM.
