[AMDGPU][DC] Bonaire - Unable to enable DC on Mobile CIK - Invalid Connector ObjectID

[Shawn Starr]

When trying an early 4.17-rc0 RPM from Fedora,

I get:

[    2.794243] [drm:construct [amdgpu]] *ERROR* construct: Invalid 
Connector ObjectID from Adapter Service for connector index:1! type 0 
expected 3

We've had issues with connector types on this laptop before and found 
some workarounds, looks like those got lost with the DC code.

my boot options: radeon.cik_support=0 amdgpu.cik_support=1 
drm_kms_helper.poll=0 amdgpu.dc=1

What information would you like me to provide?

Thanks,
Shawn.
