regtools: add graphical register explorer + analyser
This tool allows one to explore any register map. Register dumps (like produced by hwstub tools) can be loaded and decoded by the tool. Finally some analysers are provided for specific soc analysis like clock tree and emi on imx233 for example. Change-Id: Iaf81bd52d15f3e44ab4fe9bc039153fcf60cf92a
