crypto: ccp - Add a quirk to firmware update

A quirk for fixing the committed TCB version, when upgrading from a
firmware version earlier than 1.50. This is a known issue, and the
documented workaround is to load the firmware twice.

Currently, this issue requires the  following workaround:

sudo modprobe -r kvm_amd
sudo modprobe -r ccp
sudo modprobe ccp
sudo modprobe kvm_amd

Implement this workaround inside kernel by checking whether the API
version is less than 1.50, and if so, download the firmware twice.
This addresses the TCB version issue.
