Marco Trevisan (Treviño) 8d545a0b95 fpi-device: Add FpiDeviceFeature flags to FpDeviceClass
Allows drivers to define more fine grained features for devices, not
strictly depending on assumptions we can make depending on the
implemented vfuncs.

We keep this per class but could be in theory moved to each instance.

In any case, added an utility function to initialize it in the way we
can ensure that we've a consistent way for setting them across all the
devices.
