Subject: [PATCH 1/2] regulator: da9121: Constify struct regmap_config
`da9121_1ch_regmap_config` and `da9121_2ch_regmap_config` are not
modified and can be declared as const to move their data to a
read-only section.
The pointer that references those structs has been converted to const
accordingly.
