Subject: [PATCH 0/3] pinctrl: bcm/samsung/tegra: make bool code non-modular

This is the last of the pinctrl cleanups I have in my queue.  So
hopefully once these are in and any current but out-of-tree drivers
are submitted, there won't be any more examples of non-modular code
using modular infrastructure for people to inadvertently copy off of.

Nothing really new here -- if the Kconfig and/or the Makefile does
not allow building the code as modular, then we don't need to be
using module_xyz() functions and/or MODULE_XYZ macros.

Here we audit and remove such instances in three subdirectories of
the pinctrl subsystem: bcm, samsung, and tegra, which allows us
to have a positive net removal of unused code as per the diffstat.

Rather than do one commit per driver, we take advantage of the
fact that the drivers are grouped already and bundle the changes
per family, since the changes are not really deeply technical.

Build tested for allmodconfig on linux-next for arm, arm64; also
explicitly compiled each file for both arch to ensure nobody got
missed on the allmodconfig.  (there are missing renesas_sdhi syms
in today's linux-next arm but that is not caused by these changes.)

Linus - thanks for your patience in merging all these to date.

Paul.
