Merge tag 'omap-for-v5.5/dt-late-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/dt

Few late dts changes for omaps for v5.5 merge window

Let's configure omap3 rng as we can now easily do it with a dts change
only by tagging it with status = "disabled" for n900 where it's not
accessible. This improves the boot-up time with distros quite a bit with
proper entropy source around.

There's also another minor update for logicpd-torpedo that does not have
USB host pins wired.

  ARM: dts: logicpd-torpedo: Disable USB Host
