[PATCHv2 0/2] Add new SEV commands

[Janakarajan Natarajan]

This patchset adds two new SEV commands, introduced in SEV API v0.15
and v0.16 respectively.

* DOWNLOAD_FIRMWARE allows the SEV firmware to be updated if a blob newer
  than or similar to the exisiting build is available.

* GET_ID allows to query for a unique ID that can be used to retrieve the
  Chip Endorsment Key (CEK) public key signed by the AMD SEV Signing Key
  (ASK). 

v1->v2:
* Added cover letter.
* Misc changes based on Boris' feedback.
