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.

Required properties:

 - compatible : should be "invensense,mpu6050"

 - compatible : should be one of

		"invensense,mpu6050"

 		"invensense,mpu6500"

		"invensense,mpu9150"

		"invensense,icm20608"

 - reg : the I2C address of the sensor

 - interrupt-parent : should be the phandle for the interrupt controller

 - interrupts : interrupt mapping for GPIO IRQ



Optional properties:

 - mount-matrix: an optional 3x3 mounting rotation matrix



 - i2c-gate node.  These devices also support an auxiliary i2c bus.  This is

   simple enough to be described using the i2c-gate binding. See

   i2c/i2c-gate.txt for more details.
