m68knommu: make 523x QSPI platform addressing consistent
If we make all QSPI (SPI protocol) addressing consistent across all ColdFire family members then we will be able to remove the duplicated plaform data and code and use a single setup for all. So modify the ColdFire 523x QSPI addressing so that: . base addresses are absolute (not relative to MBAR peripheral register) . use a common name for IRQs used . move chip select definitions (CS) to appropriate header Signed-off-by: Greg Ungerer <gerg@uclinux.org>
