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: 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 - reg : the I2C address of the sensor
- interrupt-parent : should be the phandle for the interrupt controller - interrupt-parent : should be the phandle for the interrupt controller
- interrupts : interrupt mapping for GPIO IRQ - interrupts : interrupt mapping for GPIO IRQ
Optional properties: Optional properties:
- mount-matrix: an optional 3x3 mounting rotation matrix - 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.
