[PATCH 2/2] drm/amdgpu: fix the gb_addr_config_fields init value mismatch

[Shiwu Zhang]

For gfx_v9_4_3 specifically, before regGB_ADDR_CONFIG is overwritten
in gfx hw_init it is read out to popluate the gb_addr_config_fields
in the sw_init stage, which causes mismatch.

Fix it temporarily by using the golden value in sw_init as well.
The final fix should be by vBIOS/IFWI.
