Jarkko Nikula e4330d8bf6 ACPI / scan: Fix enumeration for special SPI and I2C devices 
Commit f406270bf7 ("ACPI / scan: Set the visited flag for all
enumerated devices") caused that two group of special SPI or I2C
devices do not enumerate. SPI and I2C devices are expected to be
enumerated by the SPI and I2C subsystems but change caused that
acpi_bus_attach() marks those devices with acpi_device_set_enumerated().

First group of devices are matched using Device Tree compatible property
with special _HID "PRP0001". Those devices have matched scan handler,
acpi_scan_attach_handler() retuns 1 and acpi_bus_attach() marks them
with acpi_device_set_enumerated().

Second group of devices without valid _HID such as "LNXVIDEO" have
device->pnp.type.platform_id set to zero and change again marks them
with acpi_device_set_enumerated().

Fix this by flagging the SPI and I2C devices during struct acpi_device
object initialization time and let the code in acpi_bus_attach() to go
through the device_attach() and acpi_default_enumeration() path for all
SPI and I2C devices.
