ENGR00215188-2 LDO bypass: disable LDO bypass before suspend and back in resume

There is one SOC bug if use LDO bypass, VDDARM_CAP will take 2ms to raise up
normal voltage when system resume back, longer than 40us before. Then it will
cause cpu hang if resume back.

Workaround:
We can disable LDO bypass at the last minute of suspend and enable LDO bypass
again as long as system resume back.
