This reverts changes introduced in commit
dd535f611d, as they broke the gsm_ppp
driver integration with PPP L2. Apparently, a more thorough
refactoring is needed to use the new interface management scheme with
PPP.

Move from using Kconfig NET_PPP_UART_NAME to a devicetree chosen
property ("zephyr,ppp-uart"). This is similar to a number of other
functions like "zephyr,shell-uart" or "zephyr,bt-uart".
As part of this we rework the init code a little to use
DEVICE_DT_GET for the modem gsm-ppp case.

CRC16 was removed by simply decreasing length of the last fragment by 2.
This worked as long as last fragment was longer than 1 byte. If not,
then last fragment was corrupted (its length ended up being 65535),
leading to undefined behavior.
Fix CRC16 removal by utilizing recently introduced
net_pkt_remove_tail(), that properly handles multiple fragments.

Introducing PPP dialup features to enable e.g. usage of nrf9160
based board as a dialup modem for transferring ip data over PPP
(e.g. windows dial up), i.e. usage of Zephyr PPP as a server for
providing MTU/MRU, IP address and DNS addresses for a PC:
- PPP LCP MRU option (configurable)
- PPP server: IPCP ip and dns address peer options to enable
providing IP and DNS addresses for PPP peer.

When PPP is muxed, using uart_poll_out resulted in each byte getting
wrapped in a muxing header. This led to UART bombardment which
can quickly cause some modems to hang and panic. This was observed
regularly using a SIMCOM7600E modem.
A perfect fix would involve rewriting ppp.c, uart_mux.c and
modem_iface_uart.c to all use another UART API, but that would be more
invasive by several orders of magnitude than this one, which utilizes
the fact that the uart_mux implementation of uart_fifo_fill does NOT
require ISR context. Since the Zephyr UART API states that the behavior
of uart_fifo_fill outside of ISR context is implementation defined, this
should be kosher.

These changes enable applications to restart the networking stack which
was previously not possible without rebooting the device. This was a
major show-stopper because it made power management impossible, and
furthermore made it impossible to recover from a bad modem state without
rebooting.
This has been verified to work on a SIMCOM7600E modem, both with and
without CONFIG_GSM_MUX enabled.

Unit tests were failing to build because random header was included by
kernel_includes.h. The problem is that rand32.h includes a generated
file that is either not generated or not included when building unit
tests. Also, it is better to limit the scope of this file to where it is
used.

ringbuf claim API returns pointer to contiguous area. In cases when data
in ringbuf wraps the end of internal buffer, then single call to claim
data is not enough to get all data - there is remaining part on the
beginning of internal buffer. Those remaining bytes will need to wait
for next ISR handler to trigger workqueue. Theoretically this means that
data on the beginning of ringbuf can wait there forever, or simply to
the next timeout in PPP stack when data traffic continues.
Consume data from ringbuf in a loop, stopping only when claiming results
in empty buffer. This will make sure that there is no stale data in the
ringbuf.

By changing the various *NET_DEVICE* macros. It is up to the device
drivers to either set a proper PM function or, if not supported or PM
disabled, to use device_pm_control_nop relevantly.
All existing macro calls are updated. Since no PM support was added so
far, device_pm_control_nop is used as the default everywhere.
