Some macros were helpers for the state initializers (e.g. to assist
UTIL_LISTIFY). In order to make the API more clear, they have been
prefixed with Z_ to emphasize they are internal and they have also been
removed from documentation.

Move all PM device runtime API calls from pm_device* to the
pm_device_runtime* namespace.
Signed-off-by: Gerard Marull-Paretas <gerard.marull@nordicsemi.no>
This patch refactors the runtime API to make it more clear and simple.
Relevant changes:
- API uses the action callback in a direct manner, avoiding unnecessary
overhead.
- API documentation has been improved to include detailed return error
codes.
- pm_runtime_disable() is now synchronous (to simplify possible error
paths) and returns error in case it fails. It is also safe to disable
in pre-kernel now.
- pm_runtime_put(_async)() will return -EALREADY if called with usage
count at zero (result of an unbalanced get/put call sequence)
- A transitional state has been added back. This makes code more
readable, and avoids using atomics (not required).
TODO:
- Solve in a better manner the asynchronous suspend error path (now
"solved" using asserts).

After the removal of pm_device_get_async, the pm_device_wait API has
become redundant. Its usage after pm_device_put_async should not be
considered a valid usecase, since after that call what will happen is a
pm_device_get (which is blocking).
Signed-off-by: Gerard Marull-Paretas <gerard.marull@nordicsemi.no>
As of today there is no clear usage of asynchronous gets, since in
general, a resume operation should be synchronous (we are about to use
the device immediately after resuming it). Removing this API simplifies
the runtime implementation in a significant way (refer to future
commits).

This commit adds minimal support of Xen hypervisor console via UART-like
driver. Implementation allows to use poll_in/poll_out char interface for
uart_console.c driver directly to HV console instead of using Xen
virtual PL011 UART. Future implementation will support interrupt driven
interface on Xen event channels, currently it is under development.
Also this commit introduces early console_io Xen interface, which allows
to receive printk/stdout messages quickly after start, but requires Xen,

Add new functionality to ztest to improve test modularity. The two
primary new entry points are:
* ztest_register_test_suite
* ztest_run_registered_test_suites
When registering a new test suite, users provide the name as well as
an optional predicate used to filter the tests for each run. Using NULL
as the predicate ensures that the test is run exactly once (after which
it is automatically filtered from future runs).
Calls to ztest_run_registered_test_suites take a state pointer as an
argument. This allows the the pragma functions to decide whether the
test should be run.
The biggest benefit of this system (other than the ability to filter
tests and maintain a larger test state) is the ability to better
modularize the test source code. Instead of all the various tests
having to coordinate and the main function having to know which tests
to run, each source file manages registering its own test
suite and handling the conditions for running the suite.

Introduce support for On-Chip Memory (OCM) areas in aarch32 Cortex-A
SoCs. This memory area is suitable for, amongst other things, un-
cached device DMA. The OCM memory can reside either at address zero
or at a high memory address, with configuration of the memory's lo-
cation similar to the configuration of the location of the exception
vectors. In both cases, it must be assured that the low/high OCM
area declaration doesn't overlap with the exception vectors memory
page at either the low/high address. Therefore, all possible OCM
location options shall be described in the SoC's device tree, the
current location shall be indicated via a "chosen" entry in the
target board's device tree.
This commit contains the necessary changes to the linker-related
files as well as the static region declaration for the MMU in-
itialization in the Zynq-7000 SoC-specific init code.

Add support for the Xilinx Zynq-7000 SoC family to this driver. This
includes some SoC-specific register accesses when setting an updated
TX clock divider, also, the device tree binding now supports higher
MDC clock divisor values when the current target SoC is a Zynq rather
than a ZynqMP.
With regards to the use of this driver in a QEMU simulation of the
Zynq-7000, the Kconfig file is modified so that the driver is not
enabled unless QEMU networking is set to Ethernet mode.

Modification of the ARM architected timer driver and its configuration
data in order to address an erratum which exists at least in the Cor-
tex-A9 CPU, and which can also be observed in the QEMU implementation
of the Cortex-A9.
Comp.: ARM Cortex-A9 processors Software Developer Errata Notice
ARM document ID032315
Erratum 740657
This erratum causes a spurious interrupt pending indication with the
interrupt controller if no new compare value is written within the
timer ISR before the interrupt is cleared. This is usually the case
in tickless mode. If the spurious interrupt is not prevented, the
timer ISR will be called twice, but on second execution, the pending
flag is not set within the timer's register space. Not handling this
issue will lead to erratic tick announcements to the kernel.
