`z_impl_k_yield` unlocked sched_spinlock, only to lock it again
immediately, do a little bit more work, then unlock it again.
This causes performance issues on SMP, where `sched_spinlock`
is often fairly highly contended and cores often end up spinning
for quite a while waiting to retake the lock in `z_swap_unlocked`.
Instead directly pass the spinlock key to `z_swap` and avoid the
extra lock+unlock.

`z_is_t1_higher_prio_than_t2` was being called twice in both the
context-switch fastpath and in `z_priq_rb_lessthan`, just to
dealing with priority ties. In addition, the API was error-prone
(and too much in the fastpath to be able to assert its invarients)
- see also #32710 for a previous example of this API breaking
and returning a>b but also b>a.
Replacing this with a direct 3-way comparison `z_cmp_t1_prio_with_t2`
sidesteps most of these issues. There is still a concern that
`sgn(z_cmp_t1_prio_with_t2(a,b)) != -sgn(z_cmp_t1_prio_with_t2(b,a))`
but I don't see any way to alleviate this aside from adding an
assert to the fastpath.

The funky order was necessary when registers were stored using a
sequence of `stp x(n), x(n+1), [sp, #-16]!`. Now that absolute offsets
are being used, we can restore natural ordering.

If next_timeout() returns INT_MAX and pass it to
z_clock_set_timeout(), and machine goes to freeze or slow down.
Bad scenario as follows:
- If an argument int32_t ticks is set large value 0xffffffff,
ticks = MAX(MIN(ticks - 1, (int32_t)MAX_TICKS), 0);
replaces it into MAX_TICKS.
- uint32_t cyc will be set near by 0xffffffff
(this is 0xfffd7280 in 100 ticks per second).
- Add adjustment to cyc, adjustment max value is MAX_CYC.
(cyc = 0xffff14fd)
- Over 0x80000000 value of uint32_t is considered as negative
value of int32_t.
if ((int32_t)(cyc + last_count - now) < MIN_DELAY)
This condition is always true.
- Because cyc += CYC_PER_TICK will get overflow, driver sets mtimecmp
near value of current mtime.
(cyc = 0x00007fc0)
- Next timer interrupt will happen soon after return from interrupt
handler.
- By repeating these events, machine cannot go to next instruction,
and it's going to freeze or slow down.

In case the endpoint string provided by the application is longer or
equal to CLIENT_EP_LEN - 1, the strncpy() function will not add the NULL
terminator. As the endpoint buffer is treated as a C-string in other
places in the code, make sure it's NULL terminated by adding NULL
explicitly at the end of the buffer.

Make sure query string used by the lwm2m_rd_client is large enough to
encode any query string that can be sent during bootstrap/registration.
As the maximum query string length is related to the endpoint name,
which is limited by `CONFIG_LWM2M_RD_CLIENT_ENDPOINT_NAME_MAX_LENGTH`,
make the query string corellated to the value of this config.

When running the tests of the async api of uart
on nucleo-l4r5zi we get MPU fault.
The reason is ordering initialization. The uart and dma
drivers are initialized PRE_KERNEL_1 while dmamux is
initialized POST_KERNEL.
Thus, the function device_get_binding fails since the
dmamux device is not ready to be used.

&i2c0 {
scl-gpios = <&gpio0 1 0>;
sda-gpios = <&gpio1 4 0>;
};
Instead of having to use:
&i2c0 {
scl-pin = <1>;
sda-pin = <36>;
};

Add some helper macros that will be convenient to use from device
drivers for accessing and error checking pin mux information in the
devicetree:
- NRF_DT_PSEL(): get a PSEL value out of the DT from either a
'foo-pin' or a 'foo-gpios' style property.
- NRF_DT_PSEL_CHECK_NOT_BOTH(), NRF_DT_PSEL_CHECK_EXACTLY_ONE():
helpers for checking that a given devicetree is OK according to
different criteria for setting PSEL properties (NAND or XOR on
whether the properties exist, respectively).
