[PATCH v2 0/6] pinctrl: add support of Airoha SoCs

[Mikhail Kshevetskiy]

This patch series add pin controller and gpio driver support for EN7523/
AN7581/AN7583 SoCs. The driver based on official linux airoha pinctrl and
gpio driver with Matheus Sampaio Queiroga <srherobrine20 at gmail.com> changes.
The changes:
 * Separate code for each SoC and keep some of the functions in
   common between them,
 * Add pinctrl driver for EN7523 SoC.

The original Matheus Sampaio Queiroga driver can be taken from the repo:
  https://sirherobrine23.com.br/airoha_an7523/kernel/commits/branch/airoha_an7523_pinctrl

Additionally in the EN7523 case the patches removes existing gpio dts nodes
and replaces them with pinctrl node. It should not be very dangerous, because:
 * No official EN7523 gpio support present in U-Boot
 * Legacy Linux EN7523 GPIO driver is mostly abandoned
 * The same driver is planned for upstream linux/openwrt

The patches were tested on EN7523/AN7581/AN7583 boards.

Changes v2:
 * pinctrl driver was split on common and per SoC parts
 * EN7523 SoC support was added
 * EN7523/AN7581 defconfigs were updated to activate
   pinctrl/gpio support
 * Board/SoC independent pinconf/pinctrl definitions
   were moved to global includes
