[PATCH 31/43] drm/amd/display: implement fw-driver interface for abm 2.4

[Rodrigo Siqueira]

From: Josip Pavic <Josip.Pavic at amd.com>

[Why]
IRAM definition needed for versions of DMCU containing ABM 2.4

[How]
Pass ABM 2.3 IRAM definition, which is compatible with ABM 2.4, to DMCU
when ABM 2.4 FW is detected
