regulator: axp20x: Migrate to regulator core's simplified DT parsing code
A common simplified DT parsing code for regulators was introduced in commit a0c7b164ad11 ("regulator: of: Provide simplified DT parsing method"). This is very similar to our own code, so get rid of ours and use the common code. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Mark Brown <broonie@kernel.org>
