iio:imu:mpu6050 update i2c bindings to reflect i2c-gate and supported parts
These bindings are somewhat lagging the state of the driver. The i2c-gate
bindings are documented elsewhere, but it seems sensible to at least have
an example and cross reference in here. SPI bindings will need to be the
subject of a future patch.
