gpio: updates for v5.14

Browse source 
- new driver for the IDT 79RC3243x GPIO controller
 - device tree bindings coversion to YAML for the following drivers:
   gpio-rk3328-grf, gpio-omap, gpio-davinci, gpio-zynq, gpio-stp, gpio-pcf857x
 - cleanup of probe functions in many drivers from Alexandru Ardelean, mostly
   dropping unnecessary calls to platform_set_drvdata() and removing error
   messages where none are needed (handled by the subsystem already)
 - several improvements to the core gpiolib and the sysfs interface code from
   Andy Shevchenko
 - conversion of the gpio-xilinx driver to using the bitmap API + improvements
   of suspend/resume handling + minor tweaks
 - convert the gpio-stmpe to using devres helpers exclusively in probe for
   improved robustness
 - updates for the generic gpio-regmap driver
 - updates for the gpio-dwapb driver
 - support for a new model in gpio-pca953x
 - cleanups in gpio-tegra186, gpio-104-idio-16, gpio-mxs & gpio-xgene
 - slight code refactoring of the gpio-zynq driver
 - documentation fixes from Mauro Carvalho Chehab
 - a bunch of minor tweaks and improvements all over the place
