core: introduce a new memory type for external dtb image

When CFG_DT=y, the external dtb image is mapped as
IO_NSEC memory type in init_external_dt function,
which may conflicts with dynamic shared memory check.
Below is the panic log with qemu boot:

	E/TC:0 0 check_phys_mem_is_outside:333 Non-sec mem (0x40000000:0x3fe00000) overlaps map (type 13 0x40000000:0x100000)
	E/TC:0 0 Panic at core/arch/arm/mm/core_mmu.c:334 <check_phys_mem_is_outside>
	E/TC:0 0 TEE load address @ 0x1bd0f000

This patch introduces a new memory type MEM_AREA_EXT_DT
which is used to map external dtb image. This memory type
will be skipped over in core_mmu_set_discovered_nsec_ddr()
in order to avoid the above panic.
