regulator: tps65910: use of_node of matched regulator being register
After getting matched regulators by using of_regulator_match(), initialize the config.of_node of regulator being register with of_regulator_match.of_node of that regulator. This is require for supporting regulator consumers in dt. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
