fpga: add lowLatencyMode setting
...
This setting improves latency by remove various checks.
Use with caution! Requires read cache in FPGA design!
The common use case in VILLASfpga is that we have exactly
one write for every read and the number of exchanged signals
do not change. If this is the case, we can reuse the buffer
descriptors during reads and write, thus avoidng freeing,
reallocating and setting them up.
We set up the descriptors in start, and in write or read,
we only reset the complete bit in the buffer descriptor and
write to the tdesc register to start the DMA transfer.
Improves read/write latency by approx. 40%.

fpga: DMA: poll BD instead of hardware register
...
polling HW is slow (>1us). Polling RAM is faster. This is a first implementation which only polls the first BD that is active. This is why this commit also removes the second read in nodes/fpga. This is not really useful anyways.

rework fpga node type
...
The various changes in fpga require a rewrite of the fpga node type.
To allow relative paths for the fpga config file, Config and SuperNode
had to be modified so they store the path of the main config file.
The syntax of the fpga node type configuration has changed - the example
config in etc has been modified accordingly.
