m42634/quant: change dead-zone from configurable to proportional

This commit removes the ability to control the quantization dead-zone
parameters since they have always been identical to the step size.

Rather than hard-coding the dead-zone size parameter to be the same as
the step size, this commit:

 - Sets the dead-zone to be ±(2 * stepsize / 3) rather than ±stepsize

 - Does not narrow the interval following the dead-zone.
