c6x: remove architecture
The c6x architecture was added to the kernel in 2011 at a time when running Linux on DSPs was widely seen as the logical evolution. It appears the trend has gone back to running Linux on Arm based SoCs with DSP, using a better supported software ecosystem, and having better real-time behavior for the DSP code. An example of this is TI's own Keystone2 platform. The upstream kernel port appears to no longer have any users. Mark Salter remained avaialable to review patches, but mentioned that he no longer has access to working hardware himself. Without any users, it's best to just remove the code completely to reduce the work for cross-architecture code changes. Many thanks to Mark for maintaining the code for the past ten years.
