Subject: [PATCH v3 0/2] Add Nitro Secure Module support

We already have support for the Nitro Enclave kernel module in upstream
Linux, which is needed to control a Nitro Enclave's lifecycle.

However, users typically want to run Linux inside the Enclave as well. To
do that well, they need the ability to communicate to the Nitro Secure
Module: A virtio based PV device that provides access to PCRs, an attestation
document as well as access to entropy.

These patches add driver support for NSM. With them in place, upstream Linux
has everything that's needed to run as a Nitro Enclave kernel.

v1 -> v2:

   - Remove boilerplate
   - Add uapi header

v2 -> v3:

   - Move globals to device struct
   - Add compat handling
   - Simplify some naming
   - Remove debug prints
   - Use module_virtio_driver
   - Ensure remove only happens on target device
   - Drop use of uio.h
