Title: FPGA - allow device detect override without an open failure

Original code works by failing to open an invalid devpath
New version doesn't attempt to open the invalid devpath
Also added the documentation (that wasn't there before)
On certain versions of windows the failure reduces the number of USB ports that can be opened by a single cgminer
Anyone using the old undocumented feature will need to change from using
icarus:/dev/ttyUSB0 to ica:/dev/ttyUSB0
bitforce:/dev/ttyUSB0 to bfl:/dev/ttyUSB0
as per the new documentation
