gpu: nvgpu: ga10b: disable elpg

Browse Source 
Engine Level Power Gating(ELPG) for ga10b is enabled
on tot for silicon. elpg needs to be enabled
only after verification on silicon and after stress
testing the feature. To avoid issues during ga10b bring-up
with unverified ELPG feature, disable it by setting both
can_elpg_init and elpg_enable to false in ga10b platform
data.
