David Hendricks 82609a3c72 stm32l: add i2c driver ...

(Derived from Vincent's original I2C slave CL)

This configures I2C port 2 as a slave device at 8-bit address 0xEC
(7-bit address is 0x76).

This CL only implements single-byte read and write transactions.
A master-initiated write will set EC mode, and a master-initiated read
will send bytes back depending on the mode.

BUG=chromium-os:28925
TEST=build on daisy and discovery; run on daisy
