Randall Spangler 3e76215df4 Fix I2C port configuration on pit ...

1) Port needs to be open-drain.  Missed this when porting from STM32F
because open-drain and alternate function are set in the same register
on STM32F and are different regs on STM32L.

2) Queue a stop condition if a transaction failed, so the clock goes
back high.

BUG=chrome-os-partner:18969
BRANCH=none
TEST=i2cscan finds both the PMU at 0x90 and the battery at 0x16
