Deepak Nibade 02943a63b4 gpu: nvgpu: rework ptimer scale APIs ...

common.ptimer unit right now exposes two APIs -
scale_ptimer() to scale the timer
ptimer_scalingfactor10x() to get the scaling factor

receiving scaling factor is not really necessary for user of
common.ptimer since it can be internally calculated in scale_ptimer()
function itself.

Hence make ptimer_scalingfactor10x() static and rename public API
scale_ptimer() to nvgpu_ptimer_scale()

nvgpu_ptimer_scale() will not accept timeout value as parameter
and return scaled timeout value in another pointer parameter.
Error code is returned if timeout value is invalid.
