gpu: nvgpu: Define functions static if DEBUG_FS=n

When turning off CONFIG_DEBUG_FS, there are build errors:
drivers/gpu/nvgpu/os/linux/os_ops_gp106.o: In function `nvgpu_fecs_trace_init_debugfs':
os_ops_gp106.c:(.text+0x8): multiple definition of `nvgpu_fecs_trace_init_debugfs'
drivers/gpu/nvgpu/os/linux/os_ops_gp10b.o:os_ops_gp10b.c:(.text+0x0): first defined here

drivers/gpu/nvgpu/os/linux/os_ops_gv100.o: In function `gp106_therm_init_debugfs':
os_ops_gv100.c:(.text+0x0): multiple definition of `gp106_therm_init_debugfs'
drivers/gpu/nvgpu/os/linux/os_ops_gp106.o:os_ops_gp106.c:(.text+0x0): first defined here

drivers/gpu/nvgpu/os/linux/os_ops_tu104.o: In function `gv100_clk_init_debugfs':
os_ops_tu104.c:(.text+0x0): multiple definition of `gv100_clk_init_debugfs'
drivers/gpu/nvgpu/os/linux/os_ops_gv100.o:os_ops_gv100.c:(.text+0x10): first defined here

This is because those functions aren't marked as static.

So this patch just simply fixes the bug.
