arm64: Fix memory shareability attribute for ioremap_wc/cache Write-combine and cacheable mappings use Normal memory on arm64. On SMP systems, the pte needs the shareability bit which is set in pgprot_default. Use this for defining PROT_DEFAULT used by ioremap_wc and ioremap_cache (Device memory is shareable by default, does not need additional attributes).
