dt-bindings:iio:imu:st,lsm6dsx: txt to yaml conversion

Straight forward conversion, but there are a few generic properties
in here like wakeup-source which should probably have schema in a
more generic location.

-* ST_LSM6DSx driver for STM 6-axis (acc + gyro) imu Mems sensors
-
-Required properties:
-- compatible: must be one of:
-  "st,lsm6ds3"
-  "st,lsm6ds3h"
-  "st,lsm6dsl"
-  "st,lsm6dsm"
-  "st,ism330dlc"
-  "st,lsm6dso"
-  "st,asm330lhh"
-  "st,lsm6dsox"
-  "st,lsm6dsr"
-  "st,lsm6ds3tr-c"
-  "st,ism330dhcx"
-  "st,lsm9ds1-imu"
-  "st,lsm6ds0"
-  "st,lsm6dsrx"
-  "st,lsm6dst"
-- reg: i2c address of the sensor / spi cs line
-
-Optional properties:
-- st,drdy-int-pin: the pin on the package that will be used to signal
-  "data ready" (valid values: 1 or 2).
-- st,pullups : enable/disable internal i2c controller pullup resistors.
-- drive-open-drain: the interrupt/data ready line will be configured
-  as open drain, which is useful if several sensors share the same
-  interrupt line. This is a boolean property.
-  (This binding is taken from pinctrl/pinctrl-bindings.txt)
-  If the requested interrupt is configured as IRQ_TYPE_LEVEL_HIGH or
-  IRQ_TYPE_EDGE_RISING a pull-down resistor is needed to drive the line
-  when it is not active, whereas a pull-up one is needed when interrupt
-  line is configured as IRQ_TYPE_LEVEL_LOW or IRQ_TYPE_EDGE_FALLING.
-- 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.
-- wakeup-source: Enables wake up of host system on event.
-
-  Refer to interrupt-controller/interrupts.txt for generic interrupt
-  client node bindings.
-
-Example:
-
-lsm6dsm@6b {
-	compatible = "st,lsm6dsm";
-	reg = <0x6b>;
-	interrupt-parent = <&gpio0>;
-	interrupts = <0 IRQ_TYPE_EDGE_RISING>;
-};
