[PATCH 5.4 027/240] linux/random.h: Remove arch_has_random, arch_has_random_seed

From: Richard Henderson <richard.henderson@linaro.org>

commit 647f50d5d9d933b644b29c54f13ac52af1b1774d upstream.

The arm64 version of archrandom.h will need to be able to test for
support and read the random number without preemption, so a separate
query predicate is not practical.

Since this part of the generic interface is unused, remove it.
