Puthikorn Voravootivat 1b52de3e3c stfm32f0: Send 0xec over i2c until get NAK from host. ...

Host i2c driver in ryu does not allow to snoop the byte
stream to abort the transaction. This make host i2c
driver to be in the dead state if the response message from
ec is shorter than host expected length.

This patch will make ec to send 0xec after end of response
message until get the 'NAK' answer from host to fixed this
issue which occur in these 2 situations.
1. When ec encounters host command error.
2. When response message is a null terminated string.

BUG=chrome-os-partner:31367
TEST='ectool version' runs fine on ryu
