ec_commands: Add "hibdelay" as an EC host command.
Currently, the only way to prevent a system from hibernating is via the
EC console command "hibdelay". This commit adds the host command
equivalent so that it can be set elsewhere. The host command takes the
amount of time in seconds to delay hibernation by and responds with the
current time in the G3 power state, the time remaining before
hibernation should be invoked, and the current setting of the
hibernation delay.
BUG=chrome-os-partner:45608
BUG=chrome-os-partner:44831
BRANCH=None
TEST=Build and flash on samus. Issue the host command from EC
console. Verify that the hibernation delay was updated by checking with
the hibdelay command.
