drm/xe/hwmon: Expose power attributes
Expose Card reactive sustained (pl1) power limit as power_max and
card default power limit (tdp) as power_rated_max.
v2:
- Fix review comments (Riana)
v3:
- Use drmm_mutex_init (Matt Brost)
- Print error value (Matt Brost)
- Convert enums to uppercase (Matt Brost)
- Avoid extra reg read in hwmon_is_visible function (Riana)
- Use xe_device_assert_mem_access when applicable (Matt Brost)
- Add intel-xe@lists.freedesktop.org in Documentation (Matt Brost)
v4:
- Use prefix xe_hwmon prefix for all functions (Matt Brost/Andi)
- %s/hwmon_reg/xe_hwmon_reg (Andi)
- Fix review comments (Guenter/Andi)
v5:
- Fix review comments (Riana)
v6:
- Use drm_warn in default case (Rodrigo)
- s/ENODEV/EOPNOTSUPP (Andi)
