The GIC interrupt controller driver is using a custom init function
called directly from the prep_c function. For consistency move that to
use SYS_INIT.

In mqtt_keepalive_time_left(), return -1 if keep alive messages are
disabled by setting CONFIG_MQTT_KEEPALIVE=0.
This allows to use mqtt_keepalive_time_left() directly as an input
for poll(). If no keep-alive is expected, -1 would indicate
that poll() can block until new data is available on the socket.

This is part of Intel VT-D and how to discover capabilities, base
addresses and so on in order to start taking advantage from it.
There is a lot to get from there, but currently we are interested only
by getting the remapping hardware base address. And more specifically
for interrupt remapping usage.
There might be more than one of such hardware so the exposed function is
made to retrieve all of them.

These implemented a k_mem_pool in terms of the now universal k_heap
utility. That's no longer necessary now that the k_mem_pool API has

Use the core k_heap API pervasively within our tree instead of the
z_mem_pool wrapper that provided compatibility with the older mempool
implementation.
Almost all of this is straightforward swapping of one alloc/free call
for another. In a few cases where code was holding onto an old-style
"mem_block" a local compatibility struct with a single field has been
swapped in to keep the invasiveness of the changes down.
Note that not all the relevant changes in this patch have in-tree test
coverage, though I validated that it all builds.

ARM64 is currently using SP_ELx as stack pointer for kernel and threads
because everything is running in EL1. If support for EL0 is required, it
is necessary to switch to use SP_EL0 instead, that is the only stack
pointer that can be accessed at all exception levels by threads.
While it is not required to keep using SP_EL0 also during the
exceptions, the current code implementation makes it easier to use the
same stack pointer as the one used by threads also during the
exceptions.
This patch moves the code from using SP_ELx to SP_EL0 and fill in the
missing entries in the vector table.

LwM2M engine by default sends piggybacked responses for requests after
all callbacks are executed. This approach however isn't good enough if
the application callback executes some lenghty operations (for instance
during FW update). Delaying the ACK may result in unnecessary
retransmissions.
This commits adds an API function which allows to send an early empty
ACK from the application callback. This prevents further retransmissions
from the server side. After all callbacks are executed, the LwM2M engine
will send the response as a separate CON message.

When using a devicetree node as an identifier we know the identifier
used to define the device structure. This allows code to directly
reference that structure, avoiding the need to look it up by label at
runtime.
Change the macros so DEVICE_DT_* device objects are globally visible
using the node identifier as the object identifier.
Also add the necessary API to verify that a device that was captured
at build time successfully completed initialization and any other
steps necessary before it can be safely used.

For devices defined using devicetree nodes we need to pass the
devicetree node, and to infer names for the device and the driver from

another level of private abstraction that accepts the information from
either source, falling back to the old parameters when the provided
node is invalid.

Introduce common API to achieve data transfer using system DMA.
"System DMA" uses the outbound memory mapped Host address,
it cannot understand Host/PCIe address.
This API will take of mapping the Host address, completing
the data transfer to/from Host memory and unmapping the window;
thus providing abstraction to the user.

For a given PCIe EP device, data transfer to/from Host memory can be
achieved with "System DMA" between mapped Host memory
(PCIe outbound memory) and EP device's local memory if EP is equipped
with a "System DMA controller".
Add public API to enable such DMA transfers.
The term "System DMA" is used to clarify that we are not talking about
dedicated "PCIe DMA"; rather the one which does not understand PCIe
address directly, and uses the mapped Host memory.
