[PATCH v2 5/7] x86/irq: Constify a struct irq_chip *

[Christophe JAILLET]

irq_data_get_irq_chip() will also return a const struct irq_chip * and some
const qualifier will also be needed in some places.

So, start to add some of these const qualifiers at the places that are
not spotted by the coccinelle script that does most of the work.

Compile tested only

If preferred, this could be done differently. If the scope of chip was
reduced, the const would be added by the cocci script in the next patch.
