592578a1dd m68knommu: Fixed GPIO pin initialization for CONFIG_M5271 FEC.
This processor only have one FEC and its MDIO pins are
located at a different offset than the code used for
the current CONFIG_M527x.

Tesed on M5271EVB eval platform.
Without this patch the FEC driver will report no PHY attached
if the bootloader does not pre-initialize the PAR_FECI2C GPIO register.

522b3d4917 m68knommu: fix 5407 ColdFire UART vector setup
There is a couple of problems with the UART vector setup for the 5307
ColdFire UART. The ICR register access should be 8bit, not 32bit. The
address of the UIVR register is wrong, it needs to be offset into the
MBAR register region. Fix these.

c7bcd0df1f m68knommu: use one exist from execption
Part of the code that did not make sense to me got removed by Greg.
This is part two:

The first compare is to check whether the interrupts are disabled or not.
Depending on the result we exectute the RESTORE_ALL macro is not only
restoring the stack but also returning to caller.
The test for pending softirq has been removed because it is allready done
in irq_exit().
Since system_call() is allso using the SAVE_ALL macro and returning via
ret_from_exception label I see no reason why we could not do this here
as well. This is also handy because if we return from the timer interrupt
and we need to resched than we check for this :)

703d01255e m68knommu: move ColdFire pit.c to its own coldfire directory
Move common ColdFire CPU pit.c to common coldfire platform directory.

Currently the common ColdFire CPU family code sits in the
arch/m68knommu/platform/5307 directory. This is confusing, the files
containing this common code are in no way specific to the 5307 ColdFire.
Create an arch/m68knommu/platform/coldfire directory to contain this

Reduce the function pointer mess of the m68knommu timer code by calling

common timer interrupt handler to the lower level hardware timer.

Ultimately this will save definitions of all these functions across all
the platform code to setup the function pointers (which for any given
m68knommu CPU family member can be only one set of hardware timer
functions).
