ASoC: Implement new DC servo readback mode for late WM8994 revisions
Later WM8994 devices implement a new DC servo readback mode with the register used to access the offset moved to register 0x59. Implement support for this and enable it on the appropriate devices. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@ti.com>
