[PATCH 0/6] platform/x86: x86-android-tablets: fix Arizona and Crystal Cove GPIO lookups

[Dmitry Torokhov]

When gpiolib dropped name-against-label matching in favor of firmware node
identity mapping, lookups referencing unattached software nodes (such as
arizona and gpio_crystalcove in x86-android-tablets) stopped working.

This series fixes the lookups and cleans up redundant software node
registrations on Lenovo tablets:
- Point Arizona GPIO property entries directly to the codec device software
  node, which is attached to the parent device.
- Hold a device reference in gpio_secondary_fwnode_init() to ensure safety
  during devres action teardown.
- Generalize gpio_secondary_fwnode_init() to accept a node group argument
  and use it to attach crystalcove_gpiochip_node as a secondary firmware
  node to INT33FD:00 on Lenovo Yoga Tab 2 models.
- Drop redundant swnode group registrations on Lenovo Yoga Tab 3 and
  Yoga Tab 2 models where codec software nodes are already registered when
  attached to their respective devices.
