Merge remote-tracking branch 'remotes/philmd-gitlab/tags/fw_cfg-20200704' into staging
firmware (and crypto) patches
- add the tls-cipher-suites object,
- add the ability to QOM objects to produce data consumable
by the fw_cfg device,
- let the tls-cipher-suites object implement the
FW_CFG_DATA_GENERATOR interface.
This is required by EDK2 'HTTPS Boot' feature of OVMF to tell
the guest which TLS ciphers it can use.
