On m68k, get_cycles() (the default implementation for random_get_entropy())
always returns zero, providing no entropy for the random driver.
Add a hook where platforms can provide their own implementation, and wire
it up in the infrastructure provided by commit
61875f30da ("random: allow architectures to
optionally define random_get_entropy()").
