spi: Add TODO comment about ACPI GPIO setup
Add a TODO comment that ideally the ACPI/gpiolib core code should take care of setting GPIO direction and/or bias according to ACPI GPIO resources. If this TODO gets implemented then the acpi_dev_gpio_irq_get() call in acpi_register_spi_device() can be dropped.
