ASoC: Remove unused AK4535 hardware read functionality
Nothing uses it and the existing hw_read operation needs to be refectored so it's easier to remove it rather than work with it. Support can be re-added if the code requires volatile registers. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
