For ease of use and accounting a condition that on SH4
pci_phys_to_bus() and pci_bus_to_phys() are one in one mappings due to
unimplemented __iomem() conversion, this change fixes access to SDRAM
memory by PCI devices.
This change also generalizes PCI system memory configuration, which is
taken from board specific defines rather than hardcoded in the PCI
host driver.

The change actually maps PCI I/O window to the same address on PCI bus
as it is stated by a comment, before the change transfers to the PCI I/O
space are failed due to misconfiguration of the most significant 14 bits
of the PCI address in PCIIOBR (note that it is set to 0x0).
Most probably the problem remained unnoticed, because communcation
to all tested PCI devices is done over PCI memory space only.
