[PATCH 0/8] drivers/pinctrl: remove truly orphaned module code

[Paul Gortmaker]

This series of commits is a part of a larger project to ensure
people don't reference modular support functions in non-modular
code.  Overall there was roughly 5k lines of dead code in the
kernel due to this.  So far we've fixed several areas, like tty,
x86, net, ... and we continue to work on other areas.

There are several reasons to not use module support for code that
can never be built as a module, but the big ones are:

 (1) it is easy to accidentally write unused module_exit and remove code
 (2) it can be misleading when reading the source, thinking it can be
     modular when the Makefile and/or Kconfig prohibit it
 (3) it requires the include of the module.h header file which in turn
     includes nearly everything else, thus adding to CPP overhead.
 (4) it gets copied/replicated into other code and spreads like weeds.

This group represents roughly 1/2 of the pinctrl commits I've got under
testing locally.  The commonality within this group is that there should
be zero runtime changes with this series, because none of the drivers
here deployed a ".remove" field which in turn would cause me to add the
".suppress_bind_attrs = true," to the driver struct.  Similarly there is
no change in the initcall ordering either.

So hopefully with that in mind it eases review.

I'm happy to have this go in via the maintainer's tree and reduce the
(large) number of patches I'm carrying locally.
