configs: Don't report CPU cores on Fiji properties
ROCm determines if a device is a dGPU in two ways. The first
is by looking at the device ID. The second is through a flag that
gets set only if the reported cpu_cores_count is 0.
If these don't agree, ROCm breaks when doing memory operations.
Previously, cpu_cores_count was non-zero on the Fiji config.
This patch sets it to 0 to appease ROCm
