Subject: ASoC: wm8994: Ensure there are enough BCLKs for four channels
Otherwise if someone tries to use all four channels on AIF1 with the
device in master mode we won't be able to clock out all the data.

Subject: ASoC: wm8994: Hold runtime PM reference while handling mic and jack

Ensures that we don't interact badly with the power management framework,
especially in the cases where we're doing deferred work or we're using a
direct GPIO for these signals.
