drm/amdgpu: break driver init process when it's bad GPU(v5)

Browse Source 
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.
