Currently the OS ignores EC panics when they occur.
After reporting a panic, the EC will force a hard reset,
possibly after a short delay. This may cause loss of data.

These patches add a handler for CrOS EC panics. When
a panic is detected the OS will attempt to flush critical
data for debugging purposes and attempt an orderly shutdown.

Changelog since v2:
- Minor updates to commit messages

Changelog since v1:
- Updated commit messages
- Split into two patches
- Moved panic handle before mkbp loop
- Switched to dev_emerg
