drm/amd/display: Fix incorrect fw_state address in dmub_srv
[ Upstream commit d60073294cc3b46b73d6de247e0e5ae8684a6241 ]
[WHY]
The fw_state in dmub_srv was assigned with wrong address.
The address was pointed to the firmware region.
[HOW]
Fix the firmware state by using DMUB_DEBUG_FW_STATE_OFFSET
in dmub_cmd.h.
