From d945d720a71858f3c65e4edd064b9ee63415d282 Mon Sep 17 00:00:00 2001

Subject: [PATCH 0860/2940] drm/amdgpu: Call doorbell index init on device
initialization
Also call functioin amdgpu_device_doorbell_init after
amdgpu_device_ip_early_init because the former depends
on the later to set up asic-specific init_doorbell_index
function
