Greg Ungerer de4cbfb599 m68knommu: remove the common interrupt controller structure
Each different m68knommu CPU interrupt controller type has its own
interrupt controller data structures now. Remove the old, and now not
used, common irq structs and init code from here.

Greg Ungerer 33a21263bf m68knommu: use common interrupt controller code for older ColdFire CPU's
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.

Greg Ungerer 277c5e3e26 m68knommu: general interrupt controller for ColdFire 532x parts
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.

Greg Ungerer 2fba4f0b03 m68knommu: general interrupt controller for ColdFire many 52xx parts
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.

Greg Ungerer cd3dd4068d m68knommu: use general interrupt controller for ColdFire 520x family
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.
