drm/xe/hwmon: Expose memory controller temperature
Expose GPU memory controller average temperature and its limits under
temp4_xxx.
Update Xe hwmon documentation for this.
v2:
- Rephrase commit message. (Badal)
- Update kernel version in Xe hwmon documentation. (Raag)
v3:
- Update kernel version in Xe hwmon documentation.
- Address review comments from Raag.
- Remove obvious comments.
- Remove redundant debug logs.
- Remove unnecessary checks.
- Avoid magic numbers.
- Add new comments.
- Use temperature sensors count to make memory controller visible.
- Use temperature limits of package for memory controller.
v4:
- Address review comments from Raag.
- Group new temperature attributes with existing temperature attributes
as per channel index in Xe hwmon documentation.
- Use DIV_ROUND_UP to calculate dwords needed for temperature limits.
- Minor aesthetic refinements.
- Remove unused TEMP_MASK_MAILBOX.
v5:
- Use REG_FIELD_GET to get count from READ_THERMAL_DATA output. (Raag)
- Change count print from decimal to hexadecimal.
- Cosmetic changes.
