PCHG: Add host command
This patch adds a host command to get the peripheral charge port
count and status.
$ ectool pchg
1
$ ectool pchg 0
State: CHARGING (4)
Battery: 50%
Flags: 0x0
$ ectool pchg 0 foo
Invalid parameter count
Usage1: pchg
Usage2: pchg <port>
Usage1 prints the number of ports.
Usage2 prints the status of a port.
$ ectool pchg 100
Bad port index
BUG=b:173235954
BRANCH=Trogdor
TEST=Done on CoachZ. See the description above.
