If we make all UART addressing consistent across all ColdFire family members
then we will be able to remove the duplicated plaform data and use a single
setup for all.

So modify the ColdFire 5206 UART addressing so that:

. UARTs are numbered from 0 up
. base addresses are absolute (not relative to MBAR peripheral register)
. use a common name for IRQs used

The reality is that you do not need the abiltity to configure the
clock divider for ColdFire CPUs. It is a fixed ratio on any given
ColdFire family member. It is not the same for all ColdFire parts,
but it is always the same in a model range. So hard define the divider
for each supported ColdFire CPU type and remove the Kconfig option.

<title>m68knommu: clean up use of MBAR for DRAM registers on ColdFire start</title>

In some of the RAM size autodetection code on ColdFire CPU startup
we reference DRAM registers relative to the MBAR register. Not all of
the supported ColdFire CPUs have an MBAR, and currently this works
because we fake an MBAR address on those registers. In an effort to
clean this up, and eventually remove the fake MBAR setting make the
DRAM register address definitions actually contain the MBAR (or IPSBAR
as appropriate) value as required.

Not all ColdFire CPUs that use the old style timer hardware module use
an MBAR set peripheral region. Move the TIMER base address defines to the
per-CPU header files where we can set it correctly based on how the
peripherals are mapped - instead of using a fake MBAR for some platforms.

The base addresses of the ColdFire DMA unit registers belong with
all the other address definitions in the per-cpu headers. The current
definitions assume they are relative to an MBAR register. Not all
ColdFire CPUs have an MBAR register. A clean address define can only
be acheived in the per-cpu headers along with all the other chips
peripheral base addresses.

The ColdFire UART base addresses varies between the different ColdFire
family members. Instead of keeping the base addresses with the UART
definitions keep them with the other addresses definitions for each
ColdFire part.

The motivation for this move is so that when we add new ColdFire
part definitions, they are all in a single file (and we shouldn't
normally need to modify the UART definitions in mcfuart.h at all).

The instruction timings of the ColdFire 54xx family parts are
different to other version 4 parts (or version 2 or 3 parts for
that matter too).

Move the instruction timing setting into the ColdFire part
specific headers, and set the 54xx value appropriately.

Move the ColdFire CPU names out of setup.c and into their repsective
headers. That way when we add new ones we won't need to modify
setup.c any more.

Add the missing 548x CPU name.

The ColdFire "timers" clock setup can be simplified. There is really no
need for the flexible per-platform setup code. The clock interrupt can be
hard defined per CPU platform (in CPU include files). This makes the
actual timer code simpler.
