drm/amdgpu: break driver init process when it's bad GPU(v5)
When retrieving bad gpu tag from eeprom, GPU init should
fail as the GPU needs to be retired for further check.
v2: Fix spelling typo, correct the condition to detect
bad gpu tag and refine error message.
v3: Refine function argument name.
v4: Fix missing check of returning value of i2c
initialization error case.
v5: Use dev_err to print PCI information in dmesg instead
of DRM_ERROR.
