Structures st_uvis25_i2c_regmap_config and st_uvis25_spi_regmap_config are local to the source and do not need to be in global scope, so make them both static. Cleans up sparse warnings: warning: symbol 'st_uvis25_i2c_regmap_config' was not declared. Should it be static? warning: symbol 'st_uvis25_spi_regmap_config' was not declared. Should it be static?
