spidev supports more communications modes
The spidev driver doesn't currently expose all SPI communications modes to
userspace. This passes them all through to the driver.
Two of them are potentially troublesome, in the sense that they could cause
hardware conflicts on shared busses. It might be appropriate to add some
privilege checks for for those modes.
