[SCSI] advansys: ioremap no longer needs page-aligned addresses 

At some point during Linux 2.1 development, ioremap() gained the ability
to handle addresses which weren't page-aligned.  Also expand the CONFIG_PCI
range to encompass that entire section of wide board initialisation, since
all wide boards are PCI.
