scsi: ufs: ufshcd-pltfrm depends on HAS_IOMEM

Building ufshcd-pltfrm.c on arch/s390/ has a linker error since S390 does
not support IOMEM, so add a dependency on HAS_IOMEM.

s390-linux-ld: drivers/scsi/ufs/ufshcd-pltfrm.o: in function `ufshcd_pltfrm_init':
ufshcd-pltfrm.c:(.text+0x38e): undefined reference to `devm_platform_ioremap_resource'

where that devm_ function is inside an #ifdef CONFIG_HAS_IOMEM/#endif
block.

        This selects the UFS host controller support. Select this if
        you have an UFS controller on Platform bus.
