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.
