core: dt_driver: move related content from dt.h to dt_driver.h

Moves so-called dt_driver related declarations and definitions from
dt.h to dt_drivers.h. Incidentally adds an inline description to
enum dt_driver_type. This change clarifies when a source file shall
include dt.h and/or dt_driver.h.

This change updates driver source files to include none, one or both of
these header files where applicable.

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
device.

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.

Add atmel shdwc driver for sama5d2. This driver uses assembly code
which expects to run from a single cache line. For the time being,
building this code is restricted to single core system since it rely
on the fact that no other cores can invalidate the TLB or the
I-cache. This driver will be used by PSCI to shutdown the SoC.
