Vic Yang 812a58825f stm32: Support backup registers and preseving reset flags ...

This CL configures backup registers and add support of preseving reset
flags in backup registers before rebooting.

BUG=chrome-os-partner:11368
TEST=On snow there's always a reset-pin flag now, so test this with
     watchdog and soft reset.

1. reset with keyboard.    flags -> reset-pin
2. trigger watchdog reset. flags -> reset-pin watchdog
3. 'reboot soft preserve'  flags -> reset-pin watchdog soft
4. trigger watchdog reset. flags -> reset-pin watchdog
5. 'reboot soft'           flags -> reset-pin soft
