Subject: [RFT PATCH 4/4] gpio: acpi: remove acpi_get_and_request_gpiod()

From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>

With no more users, we can remove acpi_get_and_request_gpiod().

- * acpi_get_and_request_gpiod - Translate ACPI GPIO pin to GPIO descriptor and

- * This function is a simple pass-through to acpi_get_gpiod(), except that

- * gpiod_get_index() for example) it also holds a reference to the GPIO device.
