[Lee Jones]

Fixes the following W=1 kernel build warning(s):

 drivers/gpu/drm/radeon/ni.c:1378:6: warning: no previous prototype for ‘cayman_cp_int_cntl_setup’ [-Wmissing-prototypes]
 1378 | void cayman_cp_int_cntl_setup(struct radeon_device *rdev,
 | ^~~~~~~~~~~~~~~~~~~~~~~~
 drivers/gpu/drm/radeon/ni.c:1732:5: warning: no previous prototype for ‘cayman_gpu_check_soft_reset’ [-Wmissing-prototypes]
 1732 | u32 cayman_gpu_check_soft_reset(struct radeon_device *rdev)
 | ^~~~~~~~~~~~~~~~~~~~~~~~~~~
