regmap-irq: handle const struct regmap_irq_sub_irq_map
The struct instances supplied by the drivers are never modified.
Handle them as const in the regmap core allowing the drivers to put them
into .rodata.
Also add a new entry to const_structs.checkpatch to make sure future
instances of this struct already enter the tree as const.
