the fix better be done by using the hpriv->base instead of iomap table:
                 void __iomem *hc_mmio = mv_hc_base_from_port(
-                               ap->host->iomap[MV_PRIMARY_BAR], hard_port);
+                                       mv_host_base(ap->host), hard_port);
                u32 hc_irq_cause, ipending;

Jeff, do the libata upper drivers use the other BARs? if not, then we can use 
pci_iomap to map BAR0, this way we can remove the iomap[] table and use one 
iomem pointer for pci and none-pci devices.
