ACPI: NUMA: Use correct type for printing addresses on i386-PAE

The addresses of NUMA nodes are not printed correctly on i386-PAE
which is misleading.

Here is a debian9-32bit with PAE in a QEMU guest having more than 4G
of memory:

qemu-system-i386 \
-hda /var/lib/libvirt/images/debian32.qcow2 \
-m 5G \
-enable-kvm \
-smp 10 \
-numa node,mem=512M,nodeid=0,cpus=0 \
-numa node,mem=512M,nodeid=1,cpus=1 \
-numa node,mem=512M,nodeid=2,cpus=2 \
-numa node,mem=512M,nodeid=3,cpus=3 \
-numa node,mem=512M,nodeid=4,cpus=4 \
-numa node,mem=512M,nodeid=5,cpus=5 \
-numa node,mem=512M,nodeid=6,cpus=6 \
-numa node,mem=512M,nodeid=7,cpus=7 \
-numa node,mem=512M,nodeid=8,cpus=8 \
-numa node,mem=512M,nodeid=9,cpus=9 \
-serial stdio

Because of the wrong value type, it prints as below:

[    0.021049] ACPI: SRAT Memory (0x0 length 0xa0000) in proximity domain 0 enabled
[    0.021740] ACPI: SRAT Memory (0x100000 length 0x1ff00000) in proximity domain 0 enabled

[    0.027118] ACPI: SRAT Memory (0x40000000 length 0x20000000) in proximity domain 8 enabled
[    0.027802] ACPI: SRAT Memory (0x60000000 length 0x20000000) in proximity domain 9 enabled

The upper half of the start address of the NUMA domains between 6
and 9 inclusive was cut, so the printed values are incorrect.

Fix the value type, to get the correct values in the log as follows:

[    0.023698] ACPI: SRAT Memory (0x0 length 0xa0000) in proximity domain 0 enabled
[    0.024325] ACPI: SRAT Memory (0x100000 length 0x1ff00000) in proximity domain 0 enabled
