RM#30920 - FT-PX2310, manual control of 10G Ethernet PHY LED

Add necessary callback-script and LED mapping for 10GBE PHY LED.

This commit updates LED mapping and adds a script which should be
used to control the LED. The script is based on the commands in
the ticket and Eduardo's work for Sphinx1.
