gpu: nvgpu: fix sparse warnings of static declaration

Fix below sparse warnings by making below APIs static :

kernel/drivers/gpu/nvgpu/gk20a/mm_gk20a.c:1795:5:
warning: symbol 'update_gmmu_pde_locked' was not declared. Should it be
static?
kernel/drivers/gpu/nvgpu/gk20a/mm_gk20a.c:1841:5:
warning: symbol 'update_gmmu_pte_locked' was not declared. Should it be
static?
