panic: Set EC_HOST_EVENT_PANIC on chipset reset

Browse Source 
Add a hook for CHIPSET_RESET to allow the EC to indicate if there is
any new panic info present. This helps coreboot to log EC panic info
in eventlog.

Also, update the hook priority for CHIPSET_RESET and HOOK_INIT to
HOOK_PRIO_LAST to allow the EC to first log any software panic before
it is checked.

BUG=b:65732924,b:69334392
BRANCH=None
TEST=Verified following:
1. Force panic_set_reason in EC on CHIPSET_RESET
2. reboot on AP console
3. mosys eventlog list shows "EC Event | Panic Reset in previous boot"
