[PATCH v2 00/15] gpio: Use modern PM macros

[Jisheng Zhang <jszhang@kernel.org>]

Use the modern PM macros for the suspend and resume functions to be
automatically dropped by the compiler when CONFIG_PM or
CONFIG_PM_SLEEP are disabled, without having to use #ifdef guards or
__maybe_unused.

This has the advantage of always compiling these functions in,
independently of any Kconfig option. Thanks to that, bugs and other
regressions are subsequently easier to catch.

Almost all drivers are converted, only gpio-tegra and gpio-mlxbf are
left as is, because the memory for saving HW context is not trivial,
if we convert them, then the two drivers' users may complain for
!CONFIG_PM && !CONFIG_PM_SLEEP case. So I didn't touch them.

patch to gpio-dwapb.c is tested on real HW, others are compile-tested only.

since v1:
  - rebase on the latest gpio/for-next branch.
  - collect Acked-by, Reviewed-by tags.
  - clarify the trival memory wasted numbers with CONFIG_PM=n in the
    dwapb's patch commit message as suggested by Andy.
  - drop patch to bt8xxx since the clean up is acchieved when switching
    to generic PCI pm framework.
