(Frodo) Several minor things

* Made i2c-voodoo3.c compile with 2.0 kernels
    It should also run without problem, but obviously I could not test it
    Changes are in the memory mapping of PCI address space
  * Removed several warning from i2c-voodoo3.c
    It compiles now without any warnings, even with WARN=1
  * Removed several warnings from matorb.c
    It compiles now without any warnings, even with WARN=1
    In the proces, I fixed one serious bug (assignment instead of comparison)
  * Removed a warning from w83781d.c
    It compiles now without any warnings, even with WARN=1

Hint: Once in a while, try to compile with WARN=1 and remove warnings. It
helps to find serious, hidden problems. Really!
