samus: panic reboot EC if PD MCU crashes
Use the EC to check if PD MCU has crashed. The EC knows this
by checking the PD status bits: if PD MCU was in RW, and is
now in RO, AND it did not get to RO via a sysjump, then it
must have crashed. When the EC detects this, the EC will also
panic and reboot the entire system, so that we can software
sync to a known good state.
Also, when EC panics due to PD crash, it will log panic info.
BUG=chrome-os-partner:36636
BRANCH=samus
TEST=load onto samus EC and PD, try sysjump'ing back and forth
on PD MCU console and verify EC does not do anything. Crash
the PD MCU when in RW by reboot command and crash divzero command,
and make sure the EC panics with PD crash panic message. Crash
the PD MCU when in RO (before sysjumping to RW) and make sure
EC does not panic.
