Summary

On recent OpenBMC firmware, the onboard ASMEDIA video card framebuffer address was removed from device tree for security purposes (value is set to zero to avoid leaking the address).
This patch works around the problem by taking framebuffer base address from "ranges" property of a parent node.

Tested on Raptor Blackbird and Talos II
