Subject: [PATCH v2 1/3] arm64: dts: ti: k3-am65-main: drop RNG clock

The x1-clk used by trng submodule comes directly from the system clock
after a fixed divider. It is always running and has a fixed frequency
that cannot be changed, making it uncontrollable. Hence this property
should be dropped from the rng node.
