motion_lid: Set tablet mode at 180 degree
This change aligns tablet mode detection in EC to match the behavior
of Chrome. When lid angle goes beyond 200 degree, tablet mode is set
to 1. On the other hand, tablet mode is set to 0 when lid angle goes
below 160 degree.
BUG=b:120050761
BRANCH=None
TEST=make -j buildall. Verified that EC reports tablet mode close to 180
degrees.
