I don't think this is a good idea: either the interface is meant
to be generic and should work with any interrupt controller, or
it is specific to one irqchip and another irqchip should provide
a different interface that has a nonconflicting name.

I suppose you want the latter here, given that the declaration
is part of the gic specific header file.
