ARM: 7418/1: LPAE: fix access flag setup in mem_type_table
A zero value for prot_sect in the memory types table implies that section mappings should never be created for the memory type in question. This is checked for in alloc_init_section(). With LPAE, we set a bit to mask access flag faults for kernel mappings. This breaks the aforementioned (!prot_sect) check in alloc_init_section(). This patch fixes this bug by first checking for a non-zero prot_sect before setting the PMD_SECT_AF flag.
