Subject: [PATCH RESEND v2 4/4] ARM: at91/dt: add trng node to at91sam9g45

From: Boris Brezillon <boris.brezillon@...e-electrons.com>

Add a DT node for the TRNG (True Random Number Generator) block.

Keep this block enabled as it does not depend on any external connection,
and thus should be available on all boards.
