spi: Add TODO comment about ACPI GPIO setup

Browse Source 
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.
