intel-gpio for v5.19-1

* Introduce helpers to iterate over GPIO chip nodes and covert some drivers

gpiolib:
 -  Introduce a helper to get first GPIO controller node
 -  Introduce gpiochip_node_count() helper
 -  Introduce for_each_gpiochip_node() loop helper

pinctrl:
 -  meson: Replace custom code by gpiochip_node_count() call
 -  meson: Enable COMPILE_TEST
 -  meson: Rename REG_* to MESON_REG_*
 -  armada-37xx: Reuse GPIO fwnode in armada_37xx_irqchip_register()
 -  armada-37xx: Switch to use fwnode instead of of_node
 -  samsung: Switch to use for_each_gpiochip_node() helper
 -  samsung: Drop redundant node parameter in samsung_banks_of_node_get()
 -  npcm7xx: Switch to use for_each_gpiochip_node() helper
 -  renesas: rza1: Switch to use for_each_gpiochip_node() helper
 -  renesas: rza1: Replace custom code by gpiochip_node_count() call
 -  stm32: Switch to use for_each_gpiochip_node() helper
 -  stm32: Replace custom code by gpiochip_node_count() call
