spi: Fixes for v5.10

This is a relatively large set of fixes, the bulk of it being a series
from Lukas Wunner which fixes confusion with the lifetime of driver data
allocated along with the SPI controller structure that's been created as
part of the conversion to devm APIs.  The simplest fix, explained in
detail in Lukas' commit message, is to move to a devm_ function for
allocation of the controller and hence driver data in order to push the
free of that after anything tries to reference the driver data in the
remove path.  This results in a relatively large diff due to the
addition of a new function but isn't particularly complex.

There's also a fix from sven van Asbroeck which fixes yet more fallout
from the conflicts between the various different places one can
configure the polarity of GPIOs in modern systems.

Otherwise everything is fairly small and driver specific.
