Make DHT22 an MCU Sensor #29

Per comment in PR #4320:

Thanks. However, the convention is to read sensor input from the "mcu" code and not directly from the host hardware. There was a similar discussion on this at PR #3462 . (And it may be possible to extend te ds18b20 code for the dh22 functionality.)

This distinction is also important because there are reports that the dht22 kernel code blocks the calling process during reads. The host code can't tolerate blocking reads - it could cause subtle failures.
