Simulink blocks tlc files tuned to reflect changes in rpp library

Until now, the model called convenience function rpp_init(), which
initialized all peripherals, even those, which vere not used. Also all
headers were included as well.

Now only those peripherals are initialized and only necessary header files
are included.

External mode seems to not work anymore and will be fixed in near future
commits.

This commit refs #916 and #917.
