dt-bindings: iio:imu:mpu6050: support more interrupt types

Browse source 
Document that the hardware supports falling edge, rising edge, level
low, and level high interrupt types, rather than just rising edge.

The language used is the same as that in st_lsm6dsx.txt.

"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
- interrupts: interrupt mapping for IRQ. It should be configured with flags
IRQ_TYPE_LEVEL_HIGH, IRQ_TYPE_EDGE_RISING, IRQ_TYPE_LEVEL_LOW or
IRQ_TYPE_EDGE_FALLING.
Refer to interrupt-controller/interrupts.txt for generic interrupt client node
bindings.
Optional properties:
- mount-matrix: an optional 3x3 mounting rotation matrix
