core: mmu: fix nsec ddr discovery regarding MEM_AREA_RAM_NSEC

Memory registered as MEM_AREA_RAM_NSEC can be part of the non-secure shared memory. This change fixes core_mmu_set_discovered_nsec_ddr() to not check such memory area do not overlap with non-secure RAM. This is no issue physical pages from MEM_AREA_RAM_NSEC memory are also handled and mapped as dynamic non-secure memory by OP-TEE.
