random: run random_int_secret_init() run after all late_initcalls
commit 47d06e532e95b71c0db3839ebdef3fe8812fca2c upstream.
The some platforms (e.g., ARM) initializes their clocks as
late_initcalls for some unknown reason. So make sure
random_int_secret_init() is run after all of the late_initcalls are
run.
