Add information about power state constraints and more information
about power management policy.

Create a separate sub group for constraint APIs. This way it is
possible to reference this api directly in the power management
reference without mess with the rest of the documentation.

Currently notification about exiting an idle state is sent before
post_ops and with interruptions locked. Change it to be sent after
exit_pos_ops callback be called.
Unfortunately it is not possible to just change the order these
functions are called since the idle thread can be scheduled out just
after irqs be unlocked and before has the chance to send the
notification, so we are locking the scheduler and unlocking it only
after the notification be sent.

The kernel expects irqs be unlocked after this function be called.
Add it to the weak function in case of the SoC or application has not
implemented it.

Allow callers to wait for an arbitrary amount of time, instead of always
waiting for a compile-time fixed period.

Removed k_pipe_block_put and static functions only related to it.
After all the old usage of k_mem_block has been replaced by k_heap,
k_pipe_block_put still taking a deprecated k_mem_block as argument
becomes dead code. All APIs that hook it from kernel.h have been
confirmed to be removed. Since an asynchronous message descriptor
is only allocated in k_pipe_block_put, static functions for pipe_
async are removed as well.

This document will show up when a viewer selects the "Security" tab, and
selects the "Security Policy". It has a brief introduction, and directs
to the official documentation of the security policy.

UARTs in Nordic devices only support a specified list of baud rates.
Choosing a different baud rate without this patch will cause a runtime
error, whereas with the constraint, this mistake is already found in
dts construction with a useful error message.

This patch includes initial support for FT800 display driver.
It includes basic features. It can be easily extended with more
FT800 display list and co-processor features.

STATUS32.DZ(bit 13) is the EV_DivZero exception enable bit, and it's
not enabled by default. we need to set it explicitly to enable divide
zero exception on early boot and each thread's setup.
The DZ bit is ignored on write and read as zero when there is no
hardware division configured. So we can simply set DZ bit even if
there is no hardware division configured.

This feature predated the tickless kernel and has been in legacy mode
for a while. We now have no drivers or systems that do not support
tickless, so remove this option and cleanup the code to only use
tickless.

This is another API that is being used in all timer drivers and is not
internal to the clock subsystem. Remove the leading z_ and make promote
it to a cross-subsystem API.

The clock/timer APIs are not application facing APIs, however, similar
to arch_ and a few other APIs they are available to implement drivers
and add support for new hardware and are documented and available to be
used outside of the clock/kernel subsystems.
Remove the leading z_ and provide them as clock_* APIs for someone
writing a new timer driver to use.
