gdb exception. New gdb uses brki r16, 0x18 that's why
we can remove old gdb support.

The external GPIO interrupts of the ColdFire 5272 SoC are edge triggered,
unlike the internal interrupt sources (which are level triggered).
Add proper support for these interrupts.

The vector field of the processors exception frame actually contains
both the vector exception number and fault status field bits.
The exception processing code was not correctly masking out the
fault status field bits before switching on the vector number.
The default case was catching the bad check, but we are reporting
the wrong kind of exception in some cases.

Add a very basic mmu-less support for coldfire m548x family. This is perhaps
also valid for m547x family. The port comprises the serial, tick timer and
reboot support. The gpio part compiles but is empty. This gives a functional
albeit limited linux for the m548x coldfire family. This has been tested
on a Freescale M548xEVB Lite board with a M5484 processor and the default
dbug monitor.

The use of __do_IRQ is deprecated, so lets stop using it.
Generally the interrupts on the supported processors here are
level triggered, so this is strait forward to switch over to
using the standard handle_level_irq flow handler. (Although
some ColdFire parts support edge triggered GPIO line interrupts
we have no support for them yet).
