The Sense HAT library talks directly to the humidity sensor via i2cdev. The overlay has always defined the humidity sensor, but the relevant kernel module wasn't being built until raspberrypi#6093, applied to 6.9 and above. We now have a kernel driver claiming the I2C address, so userspace can't talk directly to the sensor. Disable the humidity sensor in the overlays Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>

#6093, applied to 6.9 and above.
