Vic Yang b57a5fe0ed STM32L ADC driver ...

ADC module on STM32L is clocked by HSI oscillator, and thus we need to
switch to HSI if using MSI. After the conversion, if the system is not
in S0, clock is switched back to MSI again.

There are several register bits that can only be written when ADC is
powered down. For now, let's just power down the ADC after each
conversion.

Currently ADC watchdog is not working and is disabled on STM32L.

BUG=chrome-os-partner:22242
TEST=Try multiple all-channel and single-channel reads in S0 and S5.
BRANCH=None
