[PATCH] arm64: dts: renesas: ulcb-kf: add 9-asix sensor device

[Nikita Yushchenko]

This adds nodes for lsm9ds0 sensor installed on the KF board.

With this patch, the sensor data becomes available over iio sysfs
interface.

Interrupt definition is not added yet, because the interrupt lines of
lsm9ds0 are pulled to VCC on the board, which implies need for
active-low configuration. But st_sensors drivers currently can't work
with active-low interrupts on this chip.
