The ethernet pins on the 532x ColdFire CPU family are multi-function
pins. We need to enable them as ethernet pins when using the FEC
ethernet driver.

There is really no limit to the addresses which can be used by the
in*() and out*() family of IO space calls in m68k non-MMU environments.
So don't impose an artificial address limit, allow the full 32bit range.

The recent changes to the old ColdFire interrupt controller code means
we no longer need to manually unmask the timer interrupt. That is now
done in the interrupt controller code proper.

The older simple ColdFire interrupt controller has no one-to-one mapping
of interrupt numbers to bits in the interrupt mask register. Create a
mapping array that each ColdFire CPU type can populate with its available
interrupts and the bits that each use in the interrupt mask register.

The newer ColdFire 532x family of CPU's uses the old timer, but has a
newer interrupt controller. It doesn't need the special timer setup
that was required when using the older interrupt controller. Remove the
dead timer irq and level setting code, and define the hard coded vector.

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.

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

The ColdFire 532x family of parts uses 2 of the same INTC interrupt

cores that use the two region INTC interrupt controller. This includes the

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.
