The external interrupts used on the old Coldfire parts with the old style
interrupt controller can be properly mask/unmasked in the interrupt
handling code.

Currently the code that supports setting the old style ColdFire interrupt
controller mask registers is macros in the include files of each of the
CPU types. Merge all these into a set of real masking functions in the
old Coldfire interrupt controller code proper. All the macros are basically
the same (excepting a register size difference on really early parts).

Each of the ColdFire CPU platform code that used the old style interrupt
controller had its own copy of the mcf_autovector() function. They are all
the same, remove them all and create a single function in the common
coldfire/intc.c code.

Create an mcfintc.h include file with the definitions for the old style
ColdFire interrupt controller. They are only needed on CPU's that use
this old controller - so isolate them on their own.

With fully implemented interrupt controller code we don't need to do

With proper interrupt controller code in place there is no need for

The old ColdFire CPU's (5206, 5307, 5407, 5249 etc) use a simple
interrupt controller. Use common setup code for them. This addition
means that all ColdFire CPU's now have some specific type of interrupt
controller code.

The ColdFire 532x family of parts uses 2 of the same INTC interrupt
controlers used in the ColdFire 520x family. So modify the code to
support both parts. The extra code for the second INTC controler in
the case of the 520x is easily optimized away to nothing.

Create general interrupt controller code for the many ColdFire version 2
cores that use the two region INTC interrupt controller. This includes the
523x family, 5270, 5271, 5274, 5275, and the 528x families.

This code does proper masking and unmasking of interrupts. With this in
place some of the driver hacks in place to support ColdFire interrupts
can finally go away.

Create general interrupt controller code for the ColdFire 520x family,
that does proper masking and unmasking of interrupts. With this in
place some of the driver hacks in place to support ColdFire interrupts
can finally go away.

Within the ColdFire family there is a variety of different interrupt
controllers in use. Some are used on multiple parts, some on only one.
There is quite some differences in some varients, so much so that
common code for all ColdFire parts would be impossible.

This commit introduces code to support one of the newer interrupt
controllers in the ColdFire 5208 and 5207 parts. It has very simple
mask and unmask operations, so is one of the easiest to support.

It is reasonably strait forward to merge the mmu and non-mmu versions

The mmu and non-mmu versions of processor.h have a lot of common code.
This is a strait forward merge. start_thread() could be improved, but
that is not quite as strait forward, leaving for a follow on change.
