drm/radeon/kms: restore surface registers on resume.

On resume on my rv530 laptop surface cntl was left disabled, so
wierd stuff would happen with rendering to a tiled front buffer.

This checks if the surface regs are assigned to bos and reprograms
the surface registers on resume using the same path that clears
them all on init.
