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:
Before:
======
text data bss dec hex filename
27804 10016 256 38076 94bc drivers/mfd/tps65219.o

After:
=====
