ASoC: wm_hubs: Improve single ended line output enable performance
The enable of the single ended line outputs on wm_hubs devices performs better if the output is enabled prior to starting VMID. Since inactive outputs are held at VMID anyway there is little cost to doing this for unused outputs. Add callbacks into wm_hubs and keep track of which outputs are really active so we can disable them once we're active. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
