greybus: spi: add device_type field to device config
Add device_type field in device config operation to get the type of
device and try to expose less the kernel internal over greybus.
This include the spidev, spi-nor will fetch the correct nor id over
jede and a modalias that will have the previous behavior (name will set
the driver to be loaded).
As at it, fix a trivial error path and return immediately.
Tested: using gbsim and confirming that a spidev and mtd device were
created.
