From: Alistair Francis <alistair.francis@wdc.com>

Work is ongoing to support PCIe device attestation and authentication.
As part of this probing a PCIe device will require generating hashes via
the SPDM protocol to the kernel.

Linux should verify the device before enabling the device, which means we
need the crypto functions to be ready before arch initilisation (where PCIe
init happens). Move the crypto init to postcore to
ensure it's loaded before PCIe devices.

This allows us to verify the certificate chain provided by a PCIe device
via SPDM before we enable it.
