feat(uart): [IDF5.1] fixes HardwareSerial::updateBaudRate() using a baud rate higher 230400 - checks UART Clock Source (espressif#10642)

* feat(openthread): add license declaration to all soure code and examples (espressif#10631)

* feat(uart): fixes uart higher 230400 in update baudrate

* ci(pre-commit): Apply automatic fixes
