Since v3:
- Addressed Thomas and Zhao review comments
- Rename fw_cfg_init_mem_[no]dma() helpers
- Remove unused CPU properties
- Remove {multi,linux}boot.bin
- Added R-b tags

Since v2:
- Addressed Mark review comments and added his R-b tags

The versioned 'pc' and 'q35' machines up to 2.12 been marked
as deprecated two releases ago, and are older than 6 years,
so according to our support policy we can remove them.

This series only includes the 2.6 and 2.7 machines removal,
as it is a big enough number of LoC removed. Rest will
follow.

Based-on: <20250506143905.4961-1-philmd@linaro.org>
