Shawn Nematbakhsh 01e43230ca stm32f0 / stm32f3: rtc: Fix register <-> time conversion ...

us_to_rtcss() could return an invalid value when us approached 1 sec
due to precision loss in the divisor. Change the calculation order to
divide last to eliminate precision loss.

BUG=b:68185182
BRANCH=None
TEST=On scarlet, Verify hw clock closely matches reality w/ low-power idle.
Verify EC doesn't watchdog for 5 hours in S5 / G3 w/ low-power idle. Verify
suspend-stress-test still succeeds to wake device on alarm.
