I.e. EAE Arcnet cards have a PLX rotary coder, which sets the first decimal, ensuring unique devices names. This patch adds two new card feature flags to indicate which cards support LEDs and the PLX rotary coder. For EAE based cards the names still depend on the PLX rotary coder (untested, since missing EAE hardware). For Sohard based cards, this patch will result in devices being called arc0, arc1, ... (tested).
