[PATCH v2 00/13] gpiolib: Two new helpers and way toward fwnode

[Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>]

This is a spin-off of the previous work of switching GPIO library
to use fwnode instead of of_node. Here we introduce a couple of
a new macro helpers, which allows to switch some of the drivers
to use fwnode and partially fwnode APIs.

Bart, Linus, I can take it thru my tree with an immutable branch if
it's the way you prefer, otherwise please suggest on how to proceed.

Changelog v2:
- properly based, so kbuild bot may test it (LKP)
- fixed typo in the macro (Geert)
- split to two macro helpers and rename the gpiochip_count()
- tagged one of stm32 and one of meson patches (Fabien, Neil)
- unified previously standalone armada patch
- due to above rewrote the armada patch from v1 completely (Sergey)
- added a lot of a new patches
- compile tested all of them on x86
