drm/amd/display: Indirect reg read macro with shift and mask
[Why]
Recent double buffering changes for dcn2 use IX_REG_READ.
However, this macro returns the full register value, with the need to
manually shift and mask it to retrieve field data.
[How]
Create new IX_REG_GET macro that handles shift and mask.
Use this for double buffering reads instead of IX_REG_READ.
