Without virtio-rng enabled kernel 5.19 takes ages to finish
random number generator initialisation which causes
issues with ssh and other crypto related services.

+Subject: [PATCH] arm64: dts: fvp: Enable virtio-rng support
+
+The virtio-rng is available from FVP_Base_RevC-2xAEMvA version 11.17.
+Enable it since Yocto includes a recipe for a newer FVP version.
+
+Upstream-Status: Inappropriate [Yocto specific]
