m68knommu: make 5249 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 5249 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
