This adds support for the htu21 humidity and temperature sensor.
To get it to work you have to do something like this:
echo "htu21 0x40" >/sys/class/i2c-dev/i2c-1/device/new_device
for example by adding it to rc.local
Compile tested on brcm2708 and I have used an earlier version of this
patch for more than a year.

This driver supports the Bosch Sensortec BMP180/BMP280 pressure and
temperature sensors. It also supports the BME280 sensors with an
additional humidity channel.
Tested I2C and SPI modes with a BME280 sensor on a Raspberry Pi Zero W.
