Cycles: Blacklist unsupported OpenCL devices 

Due to various driver issues with AMD GCN 1 cards we can no longer support
these GPUs. This patch makes them unavailable to select for Cycles rendering.

GCN cards 2 and higher are still supported. Please use the most recent
drivers available to ensure proper functionality.

See here for a list to check which GPUs are supported:
