gpu: nvgpu: adjust the max idle filter for AELPG

Browse Source 
- When we enable AELPG, we send maximum idle threshold value
  as one of the parameters.
- This was set to 70 msec whereas the ELPG IDLE threshold
  was set to 15 msec.
- Thus, when AELPG is enabled, the threshold is getting modified
  to a much higher value. So sometimes ELPG is not getting engaged
  and this is leading to timeout in ELPG MODS 101 test on GVS.
