gpu: nvgpu: fix DVR issues in ltc unit

Browse Source 
1. Move ecc_init from public to private, since it is
   used only in init_ltc_support. Also, added description
   about initializing ltc-lts ecc counters in
   init_ltc_support function description.
2. Few documentation update to fix incorrect variable names
   and spellings.
