This patch makes reg_defaults const in the reg_config struct not in the regmap struct.
Since we duplicate the reg_config reg_defaults into the regmap reg_defaults the index cache works on a runtime allocated array. (Though I wouldn't object to see it gone. For the average uscase it uses more memory and is slower than the rbnode cache).
