core: dt: Make it possible to alter device mapping

In case where IP core device is TrustZone aware and is used by both REE
and TEE dt_map_dev() would normally cause non-secure mapping for the

When selected registers in IP core are only accessible by TrustZone device
needs to be mapped with MEM_AREA_IO_SEC to cause actual AXI memory access
be made with AWPROT[1] and ARPROT[1] bits configured properly.

This adds new argument for dt_map_dev() to enable forcing mapping to be
secure or non-secure.
