[PATCH 1 0/4] PCI: Use of_device_get_match_data() to simplify probe

This turned into much ado about nothing, but Shailendra's hisi patch
prompted similar cleanups in other drivers.  It's a minor simplification,
but I think worth doing consistently across drivers.

Basically this is Geert's observation that when the driver probe function
is called only as a result of matching something in <match_table>, a
subsequent of_match_device(<match_table>, dev) call should never fail.

Therefore, instead of this:

  struct of_device_id *match;

  match = of_match_device(<match_table>, dev);
  ... = match->data;

we can do this:

  ... = of_device_get_match_data(dev);
