arm64/mm: Drop _PROT_SECT_DEFAULT

'commit db95ea787bd1 ("arm64: mm: Wire up TCR.DS bit to PTE shareability
fields")' dropped the last reference to symbol _PROT_SECT_DEFAULT, while
transitioning from PMD_SECT_S to PMD_MAYBE_SHARED for PROT_SECT_DEFAULT.
Hence let's just drop that symbol which is now unused.
