This commit makes the driver disallow drastic clock rate changes.
These changes happen mostly in the very beginning, when the timestamp in
hardware is zeroed.
In such cases the set callback is called soon after and fixes the large
offset. Without this limit the clock offset oscillates for a longer
period before it properly syncs as the requested ratio jumps between
very large and very small values.

Bad function calls caused assertion errors in previous implementation.
This change introduces fixes to prevent those errors. In addition
nrfx_wdt_init function is moved to init function calling at the start of
zephyr.
There are additional changes. -EINVAL value is returning in install
function when watchdog timeout value is invalid (less or equal minimum
or greater than value supported by watchdog peripheral in Nordic's SoCs.
Additionaly condition to chech if low frequency clock is enabled was
removed. Watchdog peripheral requests LFCLK in hardware.

This patch changes the way the transmitter is handled in the UART
driver, so that it is activated only when there is something to send.
The current UART API does not allow to disable RX completely, since
the poll_in function description implies that UART must continuously
listen. To provide a way of disabling the entire UART and lowering the
current consumption, this patch adds the power management to the UART
driver. When instructed to enter any of the power saving states,
the driver will disable the UART, and it will enable the UART back
when it is switched again to the active state.

This enables the cc3220sf_launchxl to automatically
reconnect to the last good known access point (AP).
This method avoids the need to:
- perform a wifi scan for access points on bootup (saving power);
- include hard-coded SSID/passwords in the wifi application.
- include the wifi shell in the wifi application.
- rely on more complex provisioning methods;

Bool symbols implicitly default to 'n'.
A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though, and is
inconsistent.
This will make the auto-generated Kconfig documentation have "No
defaults. Implicitly defaults to n." as well, which is clearer than
'default n if ...'
This is basically reapplying commit 133a299b50 ("drivers: i2c: Kconfig:
Remove redundant 'default n' properties"), which has been partially
reverted in commit c7875b75aa ("i2c: stm32_v2: implement slave

The advantage to this approach allows drivers for
devices that already keep statistics data on hardware
registers to use those instead, rather than try to
replicate it the same counters again within the driver
itself.
The eth_native_posix.c driver though do not benefit
from this, is modified to use the new callback system.

The wifi_winc1500 driver's socket id is stored in
net_context->user_data, which may be overwritten later at
the socket layer, which also uses the net_context->user_data
field to store socket flags.
This patch introduces a dedicated offload_context field
for use by offload drivers, and updates the wifi_winc1500 offload
driver to use this field instead of user_data.

In case of tickless kernel, k_busy_wait() calls __enable_sys_clock()
which in turn calls _set_time() with maximum RTC counter programmable
value. This will set the expected_sys_ticks to maximum tick value even
though there is no explicit timeout is requested from the kernel or from
an application. In this scenario, if an app calls k_sleep() which in
turn calls _add_timeout() which will adjust timeout value as per the
elapsed program time which based on incorrectly set expected_sys_ticks.
To fix this issue, we should not set the expected_sys_ticks in case
of __enable_sys_clock() as it just requests to run the counter but
a timeout event request.
