Looks like omap3 RNG is similar to the omap2 rng, let's get it working by configring the dts node for it. We must also add rng_ick to core_l4_clkdm as noted by Adam Ford. And please note that the RNG is likely disabled on HS devices. At least n900 does not have it accessible, and instead omap3-rom-rng driver must be used. So let's tag RNG as disabled on n900 as noted by Pali Rohár <pali.rohar@gmail.com>. On am3517 at least the clocks need to be configured to get it working as noted by Adam Ford, so let's tag it disabled for now.
