[PATCH] arm64: head: rely on CONFIG_RANDOM_TRUST_CPU

[Andrea Righi]

The CONFIG_ARCH_RANDOM .config option has been removed by
commit 9592eef7c16e ("random: remove CONFIG_ARCH_RANDOM").

Depend on CONFIG_RANDOM_TRUST_CPU to determine whether we can rely on
__arm64_rndr() to initialize the seed for kaslr.
