[PATCH v2 0/2] driver core: provide and use device_match_fwnode_ext()

[Bartosz Golaszewski]

In GPIOLIB, during fwnode lookup, after having resolved the consumer's
reference to a specific fwnode, we only match it against the primary
node of the controllers. Let's extend that to also the secondary node by
exposing fwnode_is_primary() to drivers and reworking
gpio_chip_match_by_fwnode().

Changes in v2:
- Fold the code initially put into driver code into GPIOLIB as advised
  by Rafael
- Rework the logic as suggested by Andy
- To that end: make fwnode_is_primary() public
- Link to v1: https://patch.msgid.link/20260219-device-match-secondary-fwnode-v1-0-a64e8d4754bc@xxxxxxxxxxxxxxxx
