Alec Berg 2356870a22 mec1322: make i2c transactions faster by not sleeping task

Modify i2c driver on mec1322 to change from sleeping and waking
on i2c interrupt, to just doing a blocking wait for i2c transfer
to complete. This greatly improves the i2c transaction time on
fast busses.

BUG=chrome-os-partner:43416
BRANCH=none
TEST=test on glados. test can talk to battery and PD MCU. Use
logic analyzer to see delay between bytes during an i2c transfer.
The delay goes from ~70us to ~4us.
