mn10300: switch to GENERIC_PCI_IOMAP

The pci_iomap variant that arch/mn10300/unit-asb2305/pci-iomap.c uses differs from the generic one in that it does not use ioremap_nocache for PCI addresses. However, it turns out that PCI addresses are automatically noncached, so switching to ioremap_nocache and to the generic implementation is safe. Signed-off-by: Michael S. Tsirkin <[email protected]>
