The series of patches consists of three major changes.
First, remove redundant supply for ADDA DAI dirver. Second, revise ETDM
control including APLL dynamic switch via DAPM, so APLL can be enabled
when it is really required. Finally, AFE probe function is updated. Bus
protection change was dropped at the previous patch because the dependent
change was not accepted.
Changes since v1:
- replace unnecessary dev_info with dev_dbg
- fix dt-binging ABI breaking behavior

2.18.0
Currently, APLL is only used in ETDM module, so APLL and APLL tuner
don't need to be enabled when AFE is used. Integrate APLL control into
ETDM DAPM routes, so that APLL can be enabled when it is really required.

2.18.0
Replace register controls in snd_soc_dai_ops with snd_soc_dapm_widgets.
startup, shutdown and trigger ops are removed, and create DAPM_SUPPLY
to handle mclk, clock gating and etdm enabling. Additionally, mclk setup
sequence is also updated because of new supply enabling sequence.
