[PATCH 44/45] drm/amd/display: [FW Promotion] Release 0.0.216.0

[Tom Chung]

From: Anthony Koo <anthony.koo at amd.com>

 - Implement command interface to query ABM SW algorithm and
   HW caps. This is primarily intended as a debugging interface

 - Add new definitions for max number of histogram bins and ABM
   curve segments available in hardware

 - Add structures to retrieve caps to describe ABM HW caps
   since not all ASICs have the same number of cure segments and
   bins
