These are a bunch of devfreq fixes for panfrost that came up in a
discussion with Robin Murphy during the code-review of the lima
devfreq patches: [0]

I am only able to test patch #1 properly because the only boards with
panfrost GPU that I have are using an Amlogic SoC. We don't have
support for the OPP tables or dynamic clock changes there yet.
So patches #2 and #3 are compile-tested only.

Martin Blumenstingl (3):
  drm/panfrost: enable devfreq based the "operating-points-v2" property
  drm/panfrost: call dev_pm_opp_of_remove_table() in all error-paths
  drm/panfrost: Use the mali-supply regulator for control again
