configuring GPIOs it can get its ACPI handle and extract this information
from ACPI tables.
Currently the kernel is not able to automatically determine from which ACPI
device it should make the corresponding platform device so we need to add
the ACPI device explicitly to acpi_platform_device_ids list defined in
drivers/acpi/acpi_platform.c. This limitation is only for the platform
devices, SPI and I2C devices are created automatically as described below.
