SMPS10 has two outputs OUT1 and OUT2 and have one input IN1.
SMPS10-OUT2 is connected to SMPS10-IN1 and can be configured either
in BOOST mode or BYPASS mode. regulator_enable of SMPS10-OUT2 configures
it in BOOST mode. For BYPASS mode regulator_allow_bypass() API can be
used. SMPS10-OUT1 is connected to SMPS10-OUT2 and can be enabled using
regulator_enable().

Changes from v1:
Reversed the order of SMPS10_OUT2 and SMPS10_OUT1 since the input signal
of OUT1 is OUT2
