[PATCH v2 6/6] configs: airoha: en7523: enable pinctrl/gpio support

[Mikhail Kshevetskiy]

This enables EN7523 pin controller and gpio driver.

This patch also removes existing gpio nodes and replaces them
with pinctrl node. It should not be very dangerous, because:
 * No official EN7523 gpio support present in U-Boot
 * The same driver is planned for upstream linux/openwrt
