Soham Purkait 53a7115f98 drm/xe/xe_ras: Add RAS GPU health indicator
Add a sysfs interface that reports the current GPU health state and
lets admin users and management tools update it but is readable by all
users. Requests are routed through the sysctrl mailbox. The interface
is present only on platforms that support the GPU health indicator.

The interface is a single read/write file at the device level:

  $ cat /sys/.../device/gpu_health
  ok

  $ echo critical > /sys/.../device/gpu_health

  $ cat /sys/.../device/gpu_health
  critical
