I'm not sure as I couldn't find more details about APB, ATB and AXI on G12A:
- APB and ATB may be needed by the CoreSight bindings
(Documentation/devicetree/bindings/arm/coresight.txt)
- AXI may be needed by the VPU driver (the S912 datasheet mentions in
OSD1_AFBCD_ENABLE: "id_fifo_thrd : unsigned , default = 64, axi id
fifo threshold")

if you don't know either then I'm fine with skipping them for now, we
can still export them later.
