The is_psr_su parameter is a boolean flag indicating whether the Panel Self Refresh Selective Update (PSR SU) feature is enabled which is a power-saving feature that allows only the updated regions of the screen to be refreshed, reducing the amount of data that needs to be sent to the display.
Fixes the below with gcc W=1: drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:5257: warning: Function parameter or member 'is_psr_su' not described in 'fill_dc_dirty_rects'
