mfd: tps65219: Constify struct regmap_irq_sub_irq_map and tps65219_chip_data
'struct regmap_irq_sub_irq_map' and 'struct tps65219_chip_data' are not
modified in this driver.
Constifying these structures moves some data to a read-only section, so
increases overall security.
On a x86_64, with allmodconfig:
