It seems all of the SPI drivers want to propagate fwnode (or of_node)
of the physical device to the SPI device. Make sure we don't duplicate
it over and over in each new driver (+2 in this cycle) by making core
to take care of that. Note, similar is done already by IIO and
I²C subsystems.

There is one noticeable and quite specific case that is taken care in
the first patch and now we have a confirmation from Cirrus that everything
is okay.  The rest is just a mechanical conversion after checking that
the parent device is assigned to the same that provides the respective
fwnode.

Changelog v2:
- collected tags
- fixed W=1 warning (unused variable) in spi-dln2.c (LKP)

v1: 20260108203004.3538449-1-andriy.shevchenko@linux.intel.com

  spi: Propagate default fwnode to the SPI controller device
  spi: Drop duplicate of_node assignment
  spi: Drop duplicate fwnode assignment
