hdl/top/*/dbe_bpm_dsp_fmc130m_4ch/*: new top files (WIP)

This top file aims to demonstrate the fmc130m_4ch board
with position measurement data. It is not correct yet! Buggy!
hdl/syn/dbe_bpm_dsp_fmc130m_4ch/*: new syn files (WIP)

This is not correct yet! Buggy!
hdl/syn/*: change syn structure to a platform-specific one
hdl/syn/ml605/*: update Manifests and .xise project files

The following command was used in folder hdl/syn/:

top=$(pwd); for i in ml605/dbe_bpm_*; do echo "cd ${top}/$i/ && hdlmake2
--make-ise --ise-proj"; cd ${top}/$i/ && hdlmake2 --make-ise --ise-proj;
done
