Correct DualShock 4 HID descriptors

 -A 6 bit value had a logical maximum of 255 when the largest it can be is 63.
 -Correct a logical max value that should be 255 instead of -1.
 -Clamp the gyroscope values to -8192/8191 as these are the largest true
  orientation values.  Anything larger or smaller is just noise.
