Subject: [PATCH 1/3] dt-bindings: rng: rockchip,rk3588-rng: add rk3576-rng
 compatible

The RK3576 SoC contains another standalone TRNG implementation. While
the register map and hardware is different, it has the same
clocks/interrupts/resets as the RK3588's TRNG, so can go in the same
binding.

Add the compatible and generalise the title/description of the binding
some more.
