ASoC: ak5558: Remove redundant snd_soc_component_read32 calls
snd_soc_component_update_bits() will only update the mask bits, so remove the redundant snd_soc_component_read32(). Signed-off-by: Axel Lin <axel.lin@ingics.com> Reviewed-by: Daniel Baluta <daniel.baluta@nxp.com> Signed-off-by: Mark Brown <broonie@kernel.org>
