1. Add reading function for remote2 temperature (Fintek, F75303) 2. Modify the temp_sensors to read sensor remote1 and remote2 for nami. BUG=b:72974136 BRANCH=none TEST=Verify Nami can get thermal remote 2 data by command "ectool temps all" Change-Id: I5e4a58f20089ed5690e2a084e93e7021e80afcdc Signed-off-by: Elthan_Huang <elthan_huang@compal.corp-partner.google.com> Reviewed-on: https://chromium-review.googlesource.com/910270 Commit-Ready: Raymond Chou <raymond_chou@compal.corp-partner.google.com> Tested-by: Raymond Chou <raymond_chou@compal.corp-partner.google.com> Reviewed-by: Raymond Chou <raymond_chou@compal.corp-partner.google.com> Reviewed-by: Daisuke Nojiri <dnojiri@chromium.org> Reviewed-by: Elthan Huang <elthan_huang@compal.corp-partner.google.com>
