powervr fd00000.gpu: [drm] loaded firmware powervr/rogue_33.15.11.3_v1.fw
powervr fd00000.gpu: [drm] FW version v1.0 (build 6503725 OS)
[drm] Initialized powervr 1.0.0 20230904 for fd00000.gpu on minor 0

In general it allows the driver to be probed on TI AM625 EK, so

But I'm not sure if you maybe want to disable it by default like
other HW blocks for the (potential) boards which don't have video at all.
