[Why]
Watermark value was expected to copy to SMU
within navi10_display_config_changed(). But
navi10_display_config_changed() is never called.
As a result, the watermark value is never
copied to SMU.
[How]
At end of navi10_set_watermarks_table,
copy watermark to SMU.

Hi all,
Navi10 has been upstreamed, so I will directly mail v2 patch
to amd-gfx. Please kindly review this patch again.
Thanks,
