The original design intent with arch_sched_ipi() was that
interprocessor interrupts were fast and easily sent, so to reduce
latency the scheduler should notify other CPUs synchronously when
scheduler state changes.
This tends to result in "storms" of IPIs in some use cases, though.
For example, SOF will enumerate over all cores doing a k_sem_give() to
notify a worker thread pinned to each, each call causing a separate
IPI. Add to that the fact that unlike x86's IO-APIC, the intel_adsp
architecture has targeted/non-broadcast IPIs that need to be repeated
for each core, and suddenly we have an O(N^2) scaling problem in the
number of CPUs.
Instead, batch the "pending" IPIs and send them only at known
scheduling points (end-of-interrupt and swap). This semantically
matches the locations where application code will "expect" to see
other threads run, so arguably is a better choice anyway.

The work queue has a semi/non-standard reschedule point implemented
using k_yield(), with a check to see if the current thread is
preemptible. Just call z_reschedule_unlocked(), it has this check
internally and is the intended API for this.
Really, this is only a half fix. Ideally the schedule point and the
lock release should be atomic[1] via the more idiomatic
z_reschedule(). But that would take some surgery, so let's go with
the simpler cleanup first.
This also avoids having to duplicate logic that gets added to
reschedule points by an upcoming patch.
[1] So that they represent a condition variable and don't race at the
end. In this case the race is present but benign, since the only thing
we really want to know is that the queue thread gets a chance to run.
The only cost is an occasional duplicated/needless context switch if
two threads are racing on a submit.

In the EC application, the system may jump between two built Zephyr
images when necessary. When jumping from the current image to the other,
the firmware switches the eSPI-related pins to GPIO function at
initialization if define alt1_no_lpc_espi in def-io-conf-list.
It causes the eSPI to reset and breaks the eSPI communication after the
image jump. This patch prevents it by removing alt1_no_lpc_espi from
def-io-conf-list.

Adding a reference implementation of the Non-Volatile Memory module
needed to join any LoRaWAN network.
This NVM is based on the SETTINGS subsys to store all the required
key to join and communicate on a LoRaWAN network.
Without proper NVM, one may experience errors when using OTAA
to join the network, as the device may violate anti-replay
protection (depending on the version of LoRaWAN).
