can: can-dev: remove obsolete CAN LED support

Browse Source 
Since commit 30f3b42147 ("can: mark led trigger as broken") the
CAN specific LED support was disabled and marked as BROKEN. As the
common LED support with CONFIG_LEDS_TRIGGER_NETDEV should do this work
now the code can be removed as preparation for a CAN netdevice Kconfig
rework.

This option adds two LED triggers for packet receive and transmit
events on each supported CAN device.
Say Y here if you are working on a system with led-class supported
LEDs and you want to use them as canbus activity indicators.
