southbridge/amd/pi/hudson: Get rid of void pointer math

Pointer math with void pointers is illegal in many compilers, though it
works with GCC because it assumes size of void to be 1. Change the pointers
or add parenthesis to force a proper order that will not cause compile
errors if compiled with a different compiler, and more importantly, don't
have unsuspected side effects.

BUG=b:118484178
TEST=Build AMD Bettong.
