PhoenixMiner

Please fix support for newer drivers on linux - 19.10, 19.20.
currently miner uses -clnew 0 regardless of clkernel setting.
probably all these kernels can work if there was no check for driver version.

second thing that can be easily fixed - auto-tuning is quite slow and it is running after gpu temp reaching its limit. every time!
there is no need for this. just use gt values found during startup.

thanks in advance
