[PATCH v2 5/5] boot: Don't allow kernel_noload with compression

[Simon Glass]

It is not possible to execute the kernel in-place without loading it.
Detect this and show an error, to avoid a crash.

Changes in v2:
- Add a 'success' case to the cover letter
- Redo how the arm64 support is implemented
