This series adds the most critical cros_ec changes for newer boards
using cros_ec. Specifically:
* Fixes timing/locking issues with the previously upstreamed (but
never used upstream) cros_ec_spi driver.
* Updates the cros_ec header file to the latest version which allows
us to use newer EC features like i2c tunneling.
* Adds an i2c tunnel driver to allow communication to the EC's i2c
devices.
This _doesn't_ get the EC driver fully up to speed with what's in the
current Chromium OS trees. There are a whole slew of cleanup patches
there, an addition of an LPC transport mode, and exports of functions
to userspace. Once these patches land and we have functionality we
can continue to pick more cleanup patches.
