Merge pull request #1044 from fadushin/disable-smp-esp32c6

Disable SMP on ESP32-C6

This change brings the build of the ESP32c6 image in-line with other
uni-processor ESP32 class MCUs, making

* the ESP32c6 consistent with other builds
* Benefitting from a small performance improvement (1.3x) in the ping pong
speed test, with negligible improvement in other perf tests.
