Fill RAM with random data using xorwow.

Browse source 
xorwow provides significantly better random data, compared to previously
used function. Making it harder to predict what data RAM is filled with.
It adds a startup time of approx 80 ms, but can be compensated with
optimising other parts of the startup routine.

This changes both firmware and fpga hashes.
