Per #13610, recent changes to this driver seem to have introduced
unexpected latency regressions. This patch effectively reverts these
patches which changed the meat of the driver:
ac36886e62 drivers: nrf: timer: add inline qualifier where
inlining is intended
084363a0dc drivers: timer: nrf: refactor for speed and correctness
71882ff8c4 drivers: timer: nrf: drop unnecessary counter mask
4b24e88fa4 drivers: timer: nrf: use irq_lock instead of spinlock
While backporting these seemingly unrelated hygiene patches:
7cbdb6c5c0 drivers/timer: Restore non-tickless tick count behavior
d30c9aeafd drivers: nrf_power_clock: Migrate to DTS.

which is moved to 0x20280000 in order to guarentee global OCRAM memory

Qemu just can't handle 1000 Hz ticks. On our CI machines, CONFIG_HZ
on the host (which is the limit of timing precision for things like
idle wakeups and signal delivery, both of which qemu seems to use for
timing) is 250. When the mismatch gets this large, we start seeing
artifacts like interrupts being delivered "in the past" (i.e. code
sees a z_clock_elapsed() value of "2" ticks before getting a
z_clock_announce() call for "1").
As it happens, this test doesn't actually require timing with that
precision, it just wants "lots of context switching" to exercise the
threadsafety of the mem_pool APIs. So decrease the tick rate to the
100Hz default, but put a loop counter in the worker threads to force
them to do 10x more work, keeping the number of preemptions constant.

The workaround for nonatomic swap had yet another edge case: it would
save off the _current pointer when pending a thread so that the next
time slice interrupt could test it to see if the swap had actually
happened before assuming that _current could be rescheduled (if it
just pended itself, that's impossible). Then it would clear the
pending_current pointer so future interrupts wouldn't be confused.
BUT: it turns out that qemu, when faced with really rapid timer rates
that exceed its (host-based) timing accuracy, is perfectly willing to
"stack up" timer interrupts such the one goes pending before the
previous one is finished executing. In that case, we can enter the
SECOND timer interrupt, to try timeslicing a SECOND time, STILL before
the PendSV exception has run to actually effect the context switch.
Except this time pending_current has been cleared and we try to
reschedule the pended _current thread incorrectly. In theory real
hardware could do this too, though it would involve absolutely crazy
interrupt latency problems.
Work around this by moving the clear to the thread itself, immediately
after it wakes up from the pend call it retakes a lock and clears
pending_current if it still matches _current. That is not a perfect
fix: there remains a 2-3 instruction race at that moment where we
return from pend and before we can lock interrupts again where a timer
interrupt will see an incorrect pointer. But I hammered at this and
couldn't make qemu do that (i.e. return from a timer interrupt but
flag a new one in just a cycle or two).

Linking to API material requires knowing the pecularities of how
doxygen, sphinx, and breathe work. In an attempt to hide some of this
we're preparing the current docs to allow use of configuration defaults
that will let us more simply use a default role that will hunt for a
reference target in the various domains that are available by using a
default "role" of "all". This will let us use the simple notation
`functionname` or `typename` without fully specifying the reference as
:c:func:`functionname`.
This patch cleans up exising docs that were (incorrectly) using single
backtics where double backtics should have been used, and also found
some typos (such as a space between the role name and the reference,
such as :file: `filename`, and a missing colon such as
c:func:`functionname`)

The gperf hashtables and support functions are created
after the initial zephyr_prebuilt.elf is created, using
data found within it.
A fixed-sized amount of memory is reserved for the
program text of these support functions, as their true
size isn't possible to predict in advance and we don't
want memory addresses after them to shift. To minimize
the amount of space reserved, it seemed reasonable to
hard-code -Os.
However, on ARC, building with -Os can cause various
millicode functions from libgcc to be included in the
binary which would not be present in zephyr_prebuilt.elf
unless zephyr_prebuilt.elf was also built with -Os,
causing anything after them to be shifted, wreaking all
kinds of havoc.
Just build without hardcoding any optimization parameters.
We have checks in the linker scripts to let us know if
we have overflowed the region for the gperf support
functions anyway, so there is no danger of this failing
silently.
