[PATCH 5/7] m68knommu: make 528x QSPI platform addressing consistent

[<gerg@snapgear.com>]

From: Greg Ungerer <gerg@uclinux.org>

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 528x 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
