e1e362dc07 m68knommu: make ColdFire SYPCR and RSR register definitions absolute addresses
Make all definitions of the ColdFire Reset and System registers absolute
addresses. Currently some are relative to the MBAR peripheral region.

The various ColdFire parts use different methods to address the internal
registers, some are absolute, some are relative to peripheral regions
which can be mapped at different address ranges (such as the MBAR and IPSBAR
registers). We don't want to deal with this in the code when we are
accessing these registers, so make all register definitions the abolsute
address - factoring out whether it is an offset into a peripheral region.

This makes them all consistently defined, and reduces the occasional bugs
caused by inconsistent definition of the register addresses.

ae909ea4ad m68knommu: factor more common ColdFire cpu reset code
Most of the more modern ColdFire cores use the same code to reset the CPU
(but it is different to most of the earlier cores). Currently that is
duplicated in each of the sub-arch files. Pull out this common code and
out a single copy of it with the other common reset code.

d894b89bf7 m68knommu: factor some common ColdFire cpu reset code
A number of the early ColdFire cores use the same code to reset the CPU.
Currently that is duplicated in each of the sub-arch files. Pull out this
common code and use a single copy of it for all CPU types that use it.
