[PATCH v3] ARM: initialize jump labels before setup_machine_fdt()

[Jason A. Donenfeld]

This patch isn't needed in the end. An equivalent patch is needed on
xtensa, powerpc, arc, mips, arm32, arm64, riscv. That's a bit much and
points to a larger issue. So I'll fix this the ugly way in the
random.c code :(.
