Add tools for updating intel network cards firmware

[IAMJDA]

The documentation for the intel ixl driver states additional tools to update the firmware:

• To change the behavior of the QSFP+ ports on XL710 adapters, use the Intel QCU (QSFP+ configuration utility); installed by the sysutils/intel-qcu package.

• To update the firmware on an adapter, use the Intel Non-Volatile Memory (NVM) Update Utility; installed by the sysutils/intel-nvmupdate-10g, sysutils/intel-nvmupdate-40g, or sysutils/intel-nvmupdate-100g, package.
