The code now contains several dead assignments which are shadowed by
another assignment a few lines later.
-> This patch removes them (and possibly associated code).

The patch did not remove occurences where a register from the device is read.
If the device does not have implicit actions associated with reading from its
registers these instances could also be removed.
