From: Matti Lehtimäki <matti.lehtimaki@xxxxxxxxx>
Add support for external power block headswitch (BHS) registers.
Similarly to MSM8974 also MSM8226 has the mx voltage rail exposed as
regulator and only cx voltage rail as power domain.

Changes in v2:
- Improve description of changes
- Require mx-supply for MSM8226
- Disallow qcom,ext-bhs-reg for other platforms
