iio:gyro: bug on L3GD20H gyroscope support

The driver was not able to manage the sensor: during probe function
and wai check, the driver stops and writes: "device name and WhoAmI mismatch."
The correct value of L3GD20H wai is 0xd7 instead of 0xd4.
Dropped support for the sensor.

           Say yes here to build support for STMicroelectronics gyroscopes:
-          L3G4200D, LSM330DL, L3GD20, L3GD20H, LSM330DLC, L3G4IS, LSM330.
+          L3G4200D, LSM330DL, L3GD20, LSM330DLC, L3G4IS, LSM330.
 
           This driver can also be built as a module. If so, these modules
           will be created:
