fix(xtal): Add a way to change the XTAL frequency for SparkFun ESP32 Thing (#9844)
* fix(xtal): Add a way to change the XTAL frequency

Add support for boards like SparkFun ESP32 Thing that use 26MHz XTAL

* ci(pre-commit): Apply automatic fixes

* feat(dbg): Print the XTAL frequency in the debug report
