libfprint requires that you use the drivers present within libfprint
itself to access the hardware. You could potentially write a libfprint
driver to drive the hardware through your SPI driver, but that's not
something we could accept in libfprint unless it was generic enough (eg.
if all the fingerprint readers on Android used that same mechanism).
