ASoC: dapm: Allow regulators to bypass as well as disable when idle
Allow regulators managed via DAPM to make use of the bypass support that has recently been added to the regulator API by setting a flag SND_SOC_DAPM_REGULATOR_BYPASS. When this flag is set the regulator will be put into bypass mode before being disabled, allowing the regulator to fall into bypass mode if it can't be disabled due to other users.
