imxtools: add regtools to work with register descriptions

Browse source 
These tools allow one to read a register description in a XML
file and to produce something useful out of it. Three example
programs are written:
- tester which simply prints the register tree
- headergen which produces a set of headers with the #define
- hwemulgen which produces something for the hwemul tool (to come)
