Tweak for Ram usage (#129)

Browse Source 
* Add KNX_NO_DEFAULT_UART to avoid default uart assignation for ArduinoPlatforms and derivatives, with associated defines (HWSERIAL_NONE for stm32) to recover RAM from unused RX/TX buffers
Remove ArduinoPlatform(HardwareSerial* knxSerial) constructor, seems not useable by KnxFacade

* Restore ArduinoPlatform::ArduinoPlatform(HardwareSerial* knxSerial) constructor

* revert xxxPlatform(HardwareSerial* s) constructors
