From: Shannon Nelson <shannon.nelson at intel.com>
Add a facility to run AQ commands through the nvmupdate utility in order
to allow the update tools to interact with the FW and do special
commands needed for updates and configuration changes.
Signed-off-by: Shannon Nelson <shannon.nelson at intel.com>
