x86: fix "__udivdi3" [drivers/scsi/aha1542.ko] undefined

Commit 976e8f67 ("x86: asm/io.h: unify
virt_to_phys/phys_to_virt") changed the return of virt_to_phys from long
to phys_addr_t which is unsigned long long on a PAE platform.

So, I could suggest a fix below since isa addresses may never be above
32 bits.
