[RFC v2 0/3] Add SPDM over Storage transport support for NVMe

[Wilfred Mallawa]

This series adds support for SPDM to be used over the storage transport, as
defined by the DMTF DSP0286 [1] for NVMe. That is, using the admin
NVMe Security Send/Receive commands, support transport for SPDM as per
DSP0286 [1]. The binding specification (DSP0286) is still currently a draft
specification that has an "Expected release Q4 2024" [2].

In anticipation of it's release, this series is an RFC.

  - Addressed comments from Klaus Jensen
    - Dropped unnecessary allocation length check
    - Dropped unnecessary alloc_len alignment check
    - Fixed up `nvme_security_receive: dw10` SPSP bit-masking

  spdm: add spdm storage transport virtual header
  hw/nvme: add NVMe Admin Security SPDM support
  hw/nvme: connect SPDM over NVMe Security Send/Recv
