[PATCH] gpio: drop devm_gpio_chip_match()

[Laurent Pinchart <laurent.pinchart+renesas@xxxxxxxxxxxxxxxx>]

Commit 48207d7595d2 ("gpio: drop devm_gpiochip_remove()") dropped the
last user of drop devm_gpio_chip_match(), causing a defined but not used
compilation warning. Fix it by removing the function.
