This commit updates the `qemu_cortex_a53` platform to use the
refactored AArch64 interrupt system.
Signed-off-by: Stephanos Ioannidis <root@stephanos.io>
The current AArch64 interrupt system relies on the multi-level
interrupt mechanism and the `irq_nextlevel` public interface to invoke
the Generic Interrupt Controller (GIC) driver functions.
Since the GIC driver has been refactored to provide a direct interface,
in order to resolve various implementation issues described in the GIC
driver refactoring commit, the architecture interrupt control functions
are updated to directly invoke the GIC driver functions.
This commit also adds support for the ARMv8 cores (e.g. Cortex-A53)
that allow interfacing to a custom external interrupt controller
(i.e. non-GIC) by mapping the architecture interrupt control functions
to the SoC layer interrupt control functions when
`ARM_CUSTOM_INTERRUPT_CONTROLLER` configuration is enabled.

The current Generic Interrupt Controller (GIC) driver makes use of the
multi-level interrupt mechanism and `irq_nextlevel` public interface.
This is a less-than-ideal implementation for the following reasons:
1. The GIC is often used as the main interrupt controller for the
Cortex-A and Cortex-R family SoCs and, in this case, it is not a 2nd
level interrupt controller; in fact, it is the root interrupt
controller and therefore should be treated as such.
2. The only reason for using `irq_nextlevel` here is to interface the
architecture implementation to the interrupt controller functions.
Since there is no nesting or multiple instances of an interrupt
controller involved, there is really no point in adding such an
abstraction.
3. 2nd level topology adds many unnecessary abstractions and results
in strange coding artefacts as well as performance penalty due to
additional branching.
This commit refactors the GIC driver interface as follows:
1. Remove the current GIC driver interface based on the multi-level
interrupt mechanism and the `irq_nextlevel` public interface.
2. Define the GIC driver interface in
`include/drivers/interrupt_controller/gic.h` and allow the arch
implementation to directly invoke this interface.

Using MQTT_UTF8_LITERAL() allows to reduce code and make it less error
prone, since utf8 length is calculated automatically by the macro.
Signed-off-by: Marcin Niestroj <m.niestroj@grinn-global.com>
Contents of mqtt_3_1_0_proto_desc and mqtt_3_1_1_proto_desc were logged
with following code:
MQTT_TRC("Encoding Protocol Description. Str:%s Size:%08x.",
mqtt_proto_desc->utf8, mqtt_proto_desc->size);
This resulted in invalid log, since they were not NULL-terminated
strings. Use MQTT_UTF8_LITERAL() to initialize both utf8 strings to make
sure they are NULL-terminated now and valid to print and
log. Additionally this makes the code a bit shorter.

Since commit 22326f6d99 got in, this test
requires that so-called NOP frames (bytes of value 0) are sent when no
TX data is provided. For nRF SoCs, the over-read character (ORC) that
is sent in such case is by default configured to the value of 0xFF.
Alter configurations for nRF boards so that 0x00 is used instead.
On the occasion, remove redundant selections of driver type in those
configurations (CONFIG_SPI_x_NRF_SPI[M]=y), as such selections must
be aligned with the value of "compatible" property in corresponding
nodes in dts, so there's no much sense in having them separately here.
Correct also the SPI instance to be used for nrf51_pca10028.

We rename the z_arm_int_lib_init() function to

There is nothing about 'library' in this

z_reschedule_unlocked() is a no-op if the caller is
cooperative, because the logic that maintains the ready queue
ensures that the co-op thread is always at the front unless
some special handling is done like in k_yield(), which does
not happen here.

The loopback driver is a simple driver that can be used to
test CAN subsystems. The actual implementation sends frames
in the same thread that calls the send function.
Some libraries have problems with that behavior.
This PR implements a dedicated thread that calls the callback
for the receiving functions and a msgq in between the sender
and the TX thread.
