sh: use the the PCI channels's io_map_base
commit 43db595e8b5d78ce5ad2feab719814a76e3ad2e5 (sh: switch to GENERIC_PCI_IOMAP) failed to take into account the PCI channels's io_map_base for mapping IO BARs. This also caused a new warning on sh. Fix this, without re-introducing code duplication, by setting NO_GENERIC_PCI_IOPORT_MAP and supplying a sh-specific __pci_ioport_map.

Find out whether you have a PCI motherboard. PCI is the name of a
bus system, i.e. the way the CPU talks to the other stuff inside
