Fix a few minor issues in the HID descriptor:
- A 6 bit entry had a logical maximum of 255 when the largest it can be is 63.
- A logical max value was incorrectly being set to -1 instead of 255.
- Set the min/max of the gyroscopes to -8192/8191 as that is the range of
values which represent the true controller orientation. Any values beyond
those extents are just noise.
