drm/amd/display: Refactor watermark programming
* Replace certain register writes with register sets that overwrites the
the entire register, instead of only a field within the register.
* Add program_watermarks() entry to hubbub vtable. Hook it up to
existing functions that program watermarks.
* Add additional watermark registers.
