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.

With general interrupt controller code in place we don't need specific
unmasking code for the internal ColdFire 520x UARTs or ethernet (FEC).

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.

* create mm/init-mm.c, move init_mm there
* remove INIT_MM, initialize init_mm with C99 initializer
* unexport init_mm on all arches:

  init_mm is already unexported on x86.

  One strange place is some OMAP driver (drivers/video/omap/) which
  won't build modular, but it's already wants get_vm_area() export.
  Somebody should look there.
