inteltool: Use portable type `uint64_t` instead of `u64`

In [1] Idwer Vollering noted, that the type `u64` is not portable so
on his FreeBSD system, the following warning is shown.

    $ clang -O2 -Wall -W -I/usr/local/include   -c -o amb.o amb.c
    amb.c:441:22: error: use of undeclared identifier 'u64'
                    ambconfig_phys = ((u64)pci_read_long(dev16, 0x4c) << 32) |

The type `uint64_t` seems to be defined also on FreeBSD, so using this
fixes the warning.

Note, this warning is not reproducable with Debian Sid/unstable for
example. I have no idea why though.
