Merge patch series "vepxpress64: disable CRC32 by default and add FVP with TF-A guide"

Harrison Mutai <harrison.mutai@arm.com> says:

This patch introduces two updates to the vexpress64 project:

- Disable CRC32 by default to prevent aborts in a standard FVP setup.
- Add a guide for running FVP with TF-A, providing a clear starting point for
  users.

+ Note that TF-A outputs the built binaries into `build/fvp/release/`.

+ This setup relies on semi-hosting, as well as, having a kernel image (``Image``)
+ and ramdisk (``ramdisk.img``) in the current working directory.
