For regulator issue, One method is that just add two regulator (VDDA&VDDIO)
needed by sgtl5000 in platform code to make sgtl5000 work first.
If that I could add it in my the following patches.

Or we do not add it (just leave sgtl5000 unwork), instead, we directly
implement the full regulator support for MX28 power management?

What's your suggestion?
