xtensa: mmu: add arch_reserved_pages_update This adds arch_reserved_pages_update() which is called in k_mem_manage_init() to reserve some physical pages so they are not re-mapped. This is due to Zephyr's linker scripts for Xtensa which often puts something before z_mapped_start (aka .text, for example, vecbase). That space needs to be reserved or else k_mem_map() would be mapping those that could result in faults. Signed-off-by: Daniel Leung <daniel.leung@intel.com>
