eve: Enable tablet mode

Browse Source 
Enable basic tablet mode options using the tablet mode input.
Do not enable the lid angle mode yet as the sensors appear to
need some calibration before this is reliable.

For now TP is still disabled by EC in tablet mode, this also
needs re-evaluated and should in theory be done at the driver
level instead of by the EC.

BUG=chrome-os-partner:62223
BRANCH=none
TEST=ensure keyboard and trackpad stop at 360 position and
restored when opened
