gpu: nvgpu: make local function static

Fixed the following sparse warning by restricting the scope of
API's within file.
- gr_gk20a.c:7273: warning: symbol 'gr_gk20a_bpt_reg_info' was not declared.
                   Should it be static?
- gr_gm20b.c:1053: warning: symbol 'gr_gm20b_bpt_reg_info' was not declared.
                   Should it be static?
