misc: xilinx-sdfec: fix dependency and build error

lib/devres.c, which implements devm_ioremap_resource(), is only built
when CONFIG_HAS_IOMEM is set/enabled, so XILINX_SDFEC should depend
on HAS_IOMEM.  Fixes this build error (as seen on UML builds):

ERROR: "devm_ioremap_resource" [drivers/misc/xilinx_sdfec.ko] undefined!

Fixes: 76d83e1c3233 ("misc: xilinx-sdfec: add core driver")
