When sleep modes are used, sockets are restored from NV after boot.
If the network changes IP addresses, restore sockets maintain old network
info in the HL7800 firmware.
On boot, restored sockets should be closed to ensure new sockets
are created with updated network info.

As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.
The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.
NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

These drivers use stack buffers to hold AT command strings which are
generated at runtime using sprintk. The buffers are only sized for the
expected range of values, not the full possible range given the datatypes
involved. Values outside this expected range could cause a buffer overflow.
To mitigate this, increase the size of each buffef to hold the full range
of each parameter type.
