Should use cpuaddr instead of void *? I duno the diff.

I think void* is fine but I just want to confirm/check if this has been used/tested with a const pointer? I think it should be fine as C does allow you to cast a const void* back to a void* as long as you are explicit about it, and this is.

Just tested w:

    const void *addr1 = &msg;
    void *addr2 = &msg;
    /* Test address with const *void */
    UtAssert_ADDRESS_EQ(addr1, addr2);

and it compiled/ran/passed.
