[PATCH 24/33] drm/amd/display: Add wm ranges to clk_mgr

[Bhawanpreet Lakha]

From: Sung Lee <sung.lee at amd.com>

[WHY & HOW]
Having watermark ranges saved inside clk_mgr to be
available for debug at all times would be useful.
Add it to the clk_mgr_internal struct for reference.
Only populated for Renoir, unused for other asics.
