[PATCH 12/19] drm/radeon/evergreen: Move 'si_get_csb_*()'s prototypes to shared header

[Lee Jones]

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

 drivers/gpu/drm/radeon/si.c:5678:5: warning: no previous prototype for ‘si_get_csb_size’ [-Wmissing-prototypes]
 5678 | u32 si_get_csb_size(struct radeon_device *rdev)
 | ^~~~~~~~~~~~~~~
 drivers/gpu/drm/radeon/si.c:5710:6: warning: no previous prototype for ‘si_get_csb_buffer’ [-Wmissing-prototypes]
 5710 | void si_get_csb_buffer(struct radeon_device *rdev, volatile u32 *buffer)
 | ^~~~~~~~~~~~~~~~~
