gpu: nvgpu: gk20a: fix sparse warnings

Make functions as static to fix sparse warnings:
- $TOP/kernel/nvgpu/drivers/gpu/nvgpu/gk20a/fecs_trace_gk20a.c:93:32: warning: symbol 'gk20a_fecs_trace_get_record' was not declared. Should it be static?
- $TOP/kernel/nvgpu/drivers/gpu/nvgpu/gk20a/fecs_trace_gk20a.c:478:29: warning: symbol 'gk20a_fecs_trace_debugfs_ring_seq_ops' was not declared. Should it be static?
