We get 2 warnings when building kernel with W=1:
drivers/gpu/drm/radeon/radeon_device.c:1961:5: warning: no previous prototype for 'radeon_debugfs_init' [-Wmissing-prototypes]
drivers/gpu/drm/radeon/radeon_device.c:1966:6: warning: no previous prototype for 'radeon_debugfs_cleanup' [-Wmissing-prototypes]

In fact, both functions are declared in
drivers/gpu/drm/radeon/radeon_drv.c, but should be declared in
a header file, thus can be recognized in other file.

So this patch moves the declarations into drivers/gpu/drm/radeon/radeon.h.

Actually if I see it correctly we could also just remove the two callbacks cause they are optional and our implementations are just empty dummys.
