Add support for AES working in Galois Counter Mode.
There is a limitation related to IV size, similar to the one present in
SW implementation (crypto/gcm.c):
The only IV size allowed is 12 bytes. It will be padded by HW to the right
with 0x_0001 (up to 16 bytes - AES block size), according to

That's just bad english. The numa node value (for pci devices) is
read from the ACPI tables on the system and represents the node that
the pci_dev is connected to.

There is no point discussing NUMA for single-socket configuration.
Single socket configurations are not NUMA. In this case
