Series platform/chrome: Replace cros_ec_cmd_xfer_status | expand

Commit Message

Prashant Malani Feb. 5, 2020, 7 p.m. UTC 
Replace send_ec_host_command() with cros_ec_cmd() which does the same
thing, but is defined in a common location in platform/chrome and
exposed for other modules to use. This allows us to remove
send_ec_host_command() entirely.

Signed-off-by: Prashant Malani <pmalani@chromium.org>

Changes in v2:
- Updated to use new function name and parameter list.
