hatch: Fix lid accel rotation matrix
The rotation matrix for the lid accel sensor was incorrect which was
resulting in unreliable lid angle calculations. This then resulted in
tablet mode being constantly activated.
BUG=b:129410925
BRANCH=none
TEST=Using ec console 'accelinfo on 1000' verified lid angle now goes
from 0 to 360 and swtiches to tablet mode after crossing 180 threshold.
