arch_has_random() and arch_has_random_seed() were added in 7b878d4b48c4
"random: Add arch_has_random[_seed]()".
arch_has_random() was never used.
arch_has_random_seed() was used in arch_random_refill(), but that usage
was removed in 48d6be955a71 "random: limit the contribution of the hw
rng to at most half".
If they're not used save arch code the trouble of implementing them.
