The crossbar_domain_map/unmap callbacks need not be called same number
of times for a particular irq. But still use counting is not needed
here, because unmap(irq) gets called when irq_desc(irq) is disposed.
After this the irq is anyways unusable and have to mapped again.
There's no need to duplicate the code comment in the commit log ;-)
Ok, will change this.

Adding the above kerneldoc for unmap callback clarity.

Please re-word this.  If I were new to the driver (I am ;-) ) I would
have no idea what this means (and I don't :( )
hmm, will reword it better then..
