Add hash support
EC computes a SHA-256 hash of its RW code on boot. Also adds host and
console commands to tell the EC to recompute the hash, or hash a
different section of flash memory.
BUG=chrome-os-partner:10777
TEST=manual
1) ectool echash -> should match what the EC precomputed
2a) ectool echash recalc 0 0x10000 5
2b) on EC console, 'hash 0 0x10000 5'
2c) results should agree
3a) on ec console, 'hash 0 0x3e000' then quickly 'hash abort'
3b) ectool echash -> status should be unavailable
4) ectool echash start 0 0x3e000 6 && ectool echash && ectool echash abort && sleep 2 && ectool echash
status should be busy, then unavailable
