Ioannis Glaropoulos 85af1bd599 tests: arch: arm: do not build/run test suites for _ns boards 
Some test suites depend on determining at run-time
an available IRQ line which can then be used to execute
the test suite. This logic cannot used if the available
IRQ line is not targeting the current security state.
Therefore, filter out the _ns Cortex-m boards from
running these tests suites (i.e. when building with
CONFIG_TRUSTED_EXECUTION_NONSECURE=y) since we can not
contol the target state of the NVIC interrupt lines.

These tests suites test generic ARM features, that do
not depend on TrustZone-M configuration, so it is OK
that they are only executed on ARM platforms without
the NONSECURE configration set.

Title: Test to verify advanced features of ARM Cortex-M interrupt handling.

Description:
This test suite verifies the behavior of CONFIG_ZERO_LATENCY_IRQS and
CONFIG_DYNAMIC_DIRECT_INTERRUPTS at runtime (ARM Only)

The first test verifies the behavior of CONFIG_DYNAMIC_DIRECT_INTERRUPTS
at runtime. In particular, it tests that dynamic direct IRQs may be
installed at run-time in the software interrupt table.
Only for ARMv7-M and ARMv8-M Mainline targets.

The second test verifies the behavior of CONFIG_ZERO_LATENCY_IRQS at runtime.
In particular, it tests that IRQs configured with the IRQ_ZERO_LATENCY
flag are assigned the highest priority in the system (and, therefore,
cannot be masked-out by irq_lock()).
Only for ARMv7-M and ARMv8-M Mainline targets.

The third test verifies the behavior of the IRQ Target State API for
TrustZone-M enabled Cortex-M Mainline CPUs.

Building and Running Project:

This project outputs to the console.  It can be built and executed on QEMU as
follows:

    ninja/make run

---------------------------------------------------------------------------

Troubleshooting:

Problems caused by out-dated project information can be addressed by
issuing one of the following commands then rebuilding the project:

    ninja/make clean    # discard results of previous builds
                        # but keep existing configuration info
or
    ninja/make pristine # discard results of previous builds
                        # and restore pre-defined configuration info

---------------------------------------------------------------------------
