Herobrine: Correct the lid g-sensor's matrix configuration
The lid g-sensor placement is like:
+------------------+
| |
| +----+ |
| | O| |
| | | | O is the pin 1 marker,
| +----+ | which faces away from user.
+------------------+
/ /
/ /
/ /
/ /
+------------------+
The sensor's coordinate system is:
x
^ z
| /
|/
+-----> y
The standard reference frame is:
y
^
|
|
+-----> x
/
/
v
z
So the matrix contributing to the standard reference frame should be:
{ { 0, 1, 0},
{ 1, 0, 0},
{ 0, 0, -1} }
BRANCH=None
BUG=b:218693733
TEST=Used 'ectool motionsense lid_angle' command to check
the g-sensor's values.
Lid closed: 0
Lid half open (~45 degrees): 45
Lid open (~90 degrees): 89
