accel: glimmer: Fixed sign of accel z-axis
The accelerometer calibration routine came up with the wrong
sign for the z-axis. Fixed that bug and flipped the sign for
glimmer in the standard reference frame rotation matrix.
BUG=none
BRANCH=rambi
TEST=Tested on a glimmer. Ran calibration routine and then
verified that if the unit is sitting flat on a table with lid
open to 90, the accelometer data send to host should read:
base = 0, 0, 1024
lid = -1024, 0, 0
When the laptop is closed and flipped over, the data should
read:
base = 0, 0, -1024
lid = 0, 0, -1024
