Subject: [PATCH 1/2] mm/early_ioremap.c: Always build early_memremap_prot() in x86

In some scenarios, we'd want to specify protection attributes when we
are doing early memory map. As early_memremap_prot() is also defined in
loongarch it's better to select ARCH_USE_MEMREMAP_PROT on X86 config to
avoid redefined error.
