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.

Both drivers (rt2860 and rt3090) register themselves as "rt2860" on
loading the module.
In the very rare case of somebody having two cards in his machine, one
using rt3090 and the other one using the rt2860 driver, loading both
modules would be impossible, the second one will not be loaded as the
kernel will tell you that the driver is already registered.
This was also present with rt2870/rt3070 (with both driver registering
as "rt2870"), but the code has been merged to one driver recently.
The follwoing patch fixes this potential problem until merging of
rt2860/rt3090 code to a single driver.
