Subject: [PATCH 5.4 296/408] ARM: dts: imx6sl: fix rng node

From: Horia Geantă <horia.geanta@....com>

[ Upstream commit 82ffb35c2ce63ef8e0325f75eb48022abcf8edbe ]

rng DT node was added without a compatible string.

i.MX driver for RNGC (drivers/char/hw_random/imx-rngc.c) also claims
support for RNGB, and is currently used for i.MX25.

Let's use this driver also for RNGB block in i.MX6SL.

Fixes: e29fe21cff96 ("ARM: dts: add device tree source for imx6sl SoC")
