Subject: [PATCH v3 2/7] x86/Kconfig: Always enable ARCH_SPARSEMEM_ENABLE

From: Mateusz Jończyk <mat.jonczyk@...pl>

It appears that (X86_64 || X86_32) is always true on x86.

This logical OR directive was introduced in
commit 6ea3038648da ("arch/x86: remove depends on CONFIG_EXPERIMENTAL")
probably by a trivial mistake.

Fixes: 6ea3038648da ("arch/x86: remove depends on CONFIG_EXPERIMENTAL")
