drm/amd/pm: Return -EOPNOTSUPP when can't read power limit 



So that hwmon_attributes_visible() will see that the power2_cap
attributes should not be visible on GPUs that don't support
the get_power_limit() function.

This fixes an error when running the "sensors" command on SI.

Fixes: 12c958d1 ("drm/amd/pm: Expose ppt1 limit for gc_v9_5_0")
