[PATCH v2 4/7] irqchip: Constify some struct irq_chip *

[Christophe JAILLET]

When the 'chip' member of struct irq_data will be turned into a const
struct irq_chip, the const qualifier will be needed for local variables
that keep a reference to this field.

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.
