Add host command to set charge port override. BUG=chrome-os-partner:32003 BRANCH=Samus TEST=Manual on Samus. Insert PD charger in port1 and BC1.2 charger in port0. ./ectool --name=cros_pd chargeoverride 0 --> Charges from port 0 ./ectool --name=cros_pd chargeoverride off --> Charges from port 1 ./ectool --name=cros_pd chargeoverride dontcharge --> No charge port ./ectool --name=cros_pd chargeoverride 1 --> Charges from port 1 ./ectool --name=cros_pd chargeoverride 2 --> Correctly returns error Signed-off-by: Shawn Nematbakhsh <shawnn@chromium.org> Change-Id: Ib35f797a4a24e96fd2e3c008ace3fd6291b89d25 Reviewed-on: https://chromium-review.googlesource.com/230910 Reviewed-by: Alec Berg <alecaberg@chromium.org>
