Prevent the VF from attempting to update the GuC reset policy when
changing the wedged mode, as this operation is not supported on VFs.

Additionally, validate the wedged_mode module parameter input, update
the internal wedged.mode state only on success, and allow setting
wedged_mode=2 only in debug builds if running as PF.

v1: https://patchwork.freedesktop.org/series/148214/#rev1
v2: Replace magic numbers with definitions (Matt, Michal)
    Use helper to sanitize wedged_mode (Michal)
    Change debug messages (Michal)
    Reorder patches (Michal)
    Add fixes tag (Matt)
v3: Rename xe_device_wedged_mode_validate to
    xe_device_validate_wedged_mode (Michal)
    Make enum nameless (Michal)
    Add default field in enum (Michal)
    Change names of enum fields to match modparam description (Michal)
v4: Fix GuC reset policy update
    Replace missing magic numbers with definitions
    Update debug message
v5: Remove old rb-s from the patch that changed

Lukasz Laguna (4):
  drm/xe: Validate wedged_mode parameter and define enum for modes
  drm/xe: Don't update wedged mode in case of an error
  drm/xe/vf: Disallow setting wedged_mode=2
  drm/xe/pf: Allow wedged_mode=2 only in debug config
