This patch set enables the Hyper-V code to boot on ARM64 inside a Virtual Trust
Level. These levels are a part of the Virtual Secure Mode documented in the
Top-Level Functional Specification available at
https://learn.microsoft.com/en-us/virtualization/hyper-v-on-windows/tlfs/vsm

[V2]
- Decreased number of #ifdef's
- Updated the wording in the commit messages to adhere to the guidlines
- Sending to the correct set of maintainers and mail lists
