z_arm_exc_exit (z_arm_int_exit) requires the current execution mode to
be specified as a parameter (through r0). This is not necessary because
this value can be directly read from CPSR.
This commit modifies the exception return function to retrieve the
current execution mode from CPSR and removes all provisions for passing
the execution mode parameter.

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.

There are scenarios where there is a NAT firewall in between MQTT
client and server. In such case, the NAT TCP timeout may be shorter
than MQTT keepalive timeout and TCP timeout. The the MQTT ping
request message is dropped by the NAT firewall, so that it cannot be
received by the server, resulting in void MQTT ping response message.
There is no TCP FIN or RST at all. The application looks hang-up
until TCP timeout happens on the client side, which may take too
long.
Therefore, the event MQTT_EVT_PINGRESP is added to inform the
application that the route between client and server is still valid.

While CONFIG_ARCH_POSIX in general isn't compatible with Zephyr POSIX
subsys (because CONFIG_ARCH_POSIX itself is implemented on top of
POSIX, so there're obvious conflicts), apply workaround to allow to
at least use clock_gettime() and clock_settime() functions.
This change is grounded in upcoming support for date manipulation
commands for Zephyr shell, which are implemented using functions
above. There's no guarantee that CONFIG_ARCH_POSIX and Zephyr POSIX
subsys will coexist for any other usecase. (But the change is
relatively clean and is definitely in the right direction of
prototyping ways of such a coexistance.)

If IO APIC is in logical destination mode, local APICs compare their
logical APIC ID defined in LDR (Logical Destination Register) with
the destination code sent with the interrupt to determine whether or not
to accept the incoming interrupt.
This patch programs LDR in xAPIC mode to support IO APIC logical mode.
The local APIC ID from local APIC ID register can't be used as the
'logical APIC ID' because LAPIC ID may not be consecutive numbers hence
it makes it impossible for LDR to encode 8 IDs within 8 bits.
This patch chooses 0 for BSP, and for APs, cpu_number which is the index
to x86_cpuboot[], which ultimately assigned in z_smp_init[].
