util/intelmetool: Fix warning building with 32-bit

On a 32-bit system, pointers are 32-bit wide, and not 64-bit, resulting
in the warning below.

```
mmap.c: In function ‘map_physical_exact’:
mmap.c:26:20: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
   virt_addr = mmap((void*)mapto, len, PROT_WRITE | PROT_READ,
                    ^
```

Fix this by using compatible types.
