ARM: dts: imx6sl: fix rng node

[ 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.
