This introduces new properties to allow the user to set the satp mode,
see patch 1 for full syntax.

v5:
- Simplify v4 implementation by leveraging valid_vm_1_10_32/64, as
  suggested by Andrew
- Split the v4 patch into 2 patches as suggested by Andrew
- Lot of other minor corrections, from Andrew
- Set the satp mode N by disabling the satp mode N + 1
- Add a helper to set satp mode from a string, as suggested by Frank

v4:
- Use custom boolean properties instead of OnOffAuto properties, based
  on ARMVQMap, as suggested by Andrew

v3:
- Free sv_name as pointed by Bin
- Replace satp-mode with boolean properties as suggested by Andrew
- Removed RB from Atish as the patch considerably changed

v2:
- Use error_setg + return as suggested by Alistair
- Add RB from Atish
- Fixed checkpatch issues missed in v1
- Replaced Ludovic email address with the rivos one
