[PATCH v2 01/10] x86: Remove arch_has_random, arch_has_random_seed

[Richard Henderson <richard.henderson@xxxxxxxxxx>]

Use the expansion of these macros directly in arch_get_random_*.

These symbols are currently part of the generic archrandom.h
interface, but are currently unused and can be removed.
