Kodama: fix rotation matrix of lid sensor
Adjust the rotation matrix of lid sensor to ensure auto-rotate function
works as expected.
BUG=b:142562612
BRANCH=kukui
TEST=1. Work well in UI when rotate DUT.
2. The values returned by the accelerometers must match the axes
used by android or w3c:
https://source.android.com/devices/sensors/sensor-types,
https://www.w3.org/TR/accelerometer/#model
device on table: in_accel_z_raw >> 0 (a very large positive value)
e.g. X(65), Y(134), Z(8245)
device on its default bottom edge: in_accel_y_raw >> 0 (a very
large positive value)
e.g. X(-17), Y(8141), Z(164)
device on its default left edge: in_accel_x_raw >> 0 (a very large
positive value)
e.g. X(8107), Y(-79), Z(-174)
