dwm_enc_key_clear

Clears the encryption key and disables the encryption option if enabled. However, it only works if the key is set.

Normally, this call writes to internal flash when setting a new value. Hence, it should not be used frequently and can take hundreds of milliseconds in the worst case! Also, it requires a reset for the new configuration to take effect.
