regmap: add regmap_field_update_bits_base()
This patch adds new regmap_field_update_bits_base() which is using regmap_update_bits_base(). Current regmap_field_xxx() can be merged into it by macro. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
