mfd: constify regmap_irq_chip structures 



Declare regmap_irq_chip structures as const as they are only stored
in the regmap_irq_chip field of a rk808 structure. This field is of
type const, so regmap_irq_chip structures having this property can be
made const too.
Done using Coccinelle:

@r disable optional_qualifier@
identifier x;
position p;
@@
static struct regmap_irq_chip x@p={...};

@ok@
struct rk808 a;
identifier r.x;
position p;
@@
a.regmap_irq_chip=&x@p;

@bad@
position p != {r.p,ok.p};
identifier r.x;

x@p

@depends on !bad disable optional_qualifier@
identifier r.x;

+const
struct regmap_irq_chip x;
