[SCSI] Change Kconfig option from IOMAPPED to MMIO
Most of the Kconfig options for switching between IO Port and MMIO operations use the opposite sense from sym2. Really, this option should be set at a chipset level rather than per-driver. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
