drm/xe/hwmon: document DG2 fan speed reporting quirk
On DG2 the driver always shows two fan channels, because the
FSC_READ_NUM_FANS command does not work on some cards. OEMs decide how
the fans map to tach channels, so two fans can share one tach line.
When that happens, the second channel reads 0 RPM even though the fan
is spinning.

Note this on the fan2_input ABI entry so the steady 0 RPM is not
mistaken for a driver bug.
