leds: is31fl319x: Constify struct regmap_config
'is31fl3190_regmap_config' and 'is31fl3196_regmap_config' are not modified
in this diver and are only used as a const struct regmap_config.
Constifying these structures moves some data to a read-only section, so
increase overall security.
On a x86_64, with allmodconfig:
