core: interrupt: registering interrupt providers

Adds interrupt chip framework API functions for an interrupt controller
to register as an interrupt provider in the driver probing sequence
based on device tree. This allows interrupt consumer to be deferred
when a dependent interrupt controller is not yet initialized.

Interrupt controllers register a driver in DT_DRIVER providers list
with: interrupt_register_provider().

Interrupt consumer can get their interrupt through DT data with
interrupt_dt_get(), interrupt_dt_get_by_index() or
interrupt_dt_get_by_name().

This change removes inclusion of interrupt.h from kernel/dt.h as it is
not needed and conflicts with inclusion of kernel/dt.h from
kernel/interrupt.h.

Moves so-called dt_driver related declarations and definitions from

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.
