Refactor reset reasons
Reasons are really bitflags, not a single reason. This will make it
easier to implement flash protection on LM4, where hibernate is a
subset of power-on reasons.
Also added some additional flags we pass in a hibernate register so...
1) We don't recognize spurious RTC wake reasons
2) Hard reset via system_reset(1) is detected as a hard reset, not a RTC wake
BUG=chrome-os-partner:11368
TEST=manual
1. Keyboard reset = power-on reset-pin
2. Pull battery = power-on
3. reboot = soft
4. reboot hard = power-on rtc-alarm
5. hibernate 10 then push power button = power-on wake-pin
6. reboot 3 sec later = soft
7. hibernate 1 = power-on rtc-alarm
