chip/stm32: Fix bug that LPTIM_PERIOD_US became unsigned long.
Due to a refactoring of bit shifts (BIT macro), LPTIM_PERIOD_US changed
from int to unsigned int, which in turn changed behavior of
set_lptim_event. This causes a watchdog reset during a long suspend. In
particular, this caused the stm32h7 FPMCU to reboot during long suspend
and fingerprint unlock to not work.
BUG=b:140538084
BRANCH=none
TEST=verified that FPMCU no longer reboots during deep sleep, fingerprint
unlock works after deep sleeping for a whole night.
