regulator: palmas: model SMPS10 as two regulators
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().
