Removed power 3v3 options (#1022)

* Removed power 3v3 options

Per skotopes, "3.3V: this line is used to power SD-Card it is highly unrecommended to turn this line off(power will be re-enabled to scan sdcard). We will remove this command in future releases."

So I removed it here. No longer an option and should not be possible.

* Added Debug Flag Detect

When debug is enabled, "power 3v3" can be used and is shown in the help for "power" menu. When debug is disabled, will not show up and cannot be executed!

* Update power_cli.c
