cr50: Split EC state machine into its own file
The device state machines aren't quite similar enough to use common
code. Split the EC state machine out, the way we split out BattPrsnt
and CCD_MODE.
BUG=b:35587387
BRANCH=cr50
TEST=manual
Pull CCD_MODE_L high, so Cr50 detects/enables CCD
Pull EC_DETECT high.
reboot -> 'EC RX only', then 'EC on' at 1 second
Pull EC_DETECT low --> See 'EC off' message
ccd --> EC UART disabled
Pull EC_DETECT high --> See 'EC on' message
ccd --> EC UART RX+TX
Pull EC_DETECT low for <1 sec then back high
(don't see EC off/on messages)
ccd --> EC UART RX+TX
Reboot with EC_DETECT still low -> EC off at 1 second
Reboot with EC_DETECT still low and then assert EC_DETECT
within a second -> EC RX only, then EC connect at 1 second.
