Subject: [PATCH v2 1/6] arm64: dts: imx8mq-librem5: describe the voice coil motor for focus control

Describe the focus motor that will be used for the rear camera - even
though the rear camera sensor driver is not yet in the mainline. The
focus motor is a separate device and can be controlled already.
