spi: Updates for v4.1

Only one framework update this time around, a change from Lars-Peter to
move full to pm_ops and remove the legacy bus PM ops. Otherwise it's
all driver updates:

- Make the spidev driver complain loudly if registered as spidev with
DT rather than with a compatible string, hopefully helping people
avoid making that mistake.
- Error handling and robustness fixes for the Designware and Intel MID
drivers from Andy Shevchenko.
- Substantial performance improvements for the Raspberry Pi driver from
Martin Sperl.
- Several new features for spidev_test from Adrian Remonda and Ian
