Remove receive and transmit timeouts which are no
longer useful as the RECEIVE_READY and
TRANSMIT_IDLE events will be used to efficiently
manage timeouts between transmit/receive calls.
Then update the the in-tree drivers using the

This commit implements parsing of the CESQ extended signal quality AT

It's used in the U-blox SARA-R5 modem instance. Furthermore, the IMEI,
IMSI is extracted in the same modem.

The modem_cellular.c driver now uses a common script to get
signal strenght, which is run on demand. This is more efficient
than polling it, and simpler since every modem doesn't have to
define their own variant of the script.
Additionally, the CSQ handler now stores the "raw" rssi value
returned from AT+CSQ to be parsed by the cellular_modem_get_signal
implementation.

This commit adds a timeout of 300ms to the generic (gsm_ppp) init

This commit improves the usage of the bus pipe (connected
to UART) to only open it when the modem is actually
powered and ready, not when leaving the idle state. This
ensures the pipe is flushed before sending the init script,
and re-enables the UART driver if it is disabled due to
errors.
While building a test platform based on the nRF9160 and a
Quectel BG95, it was discovered that the nRF9160 correctly
throws UART errors if the RX is enabled while the UART RX
line is low (which was due to the modem being powered
down).
The improvements should also help help remove the
"<wrn> modem_chat: receive buffer overrun" warning which
would occur during startup as the pipe was opened, but
nothing was receiving the data, causing the buffer to
overflow.

Modify the signature of the k_mem_slab_free() function with a new one,
replacing the old void **mem with void *mem as a parameter.
The following function:
void k_mem_slab_free(struct k_mem_slab *slab, void **mem);
has the wrong signature. mem is only used as a regular pointer, so there
is no need to use a double-pointer. The correct signature should be:
void k_mem_slab_free(struct k_mem_slab *slab, void *mem);
The issue with the current signature, although functional, is that it is
extremely confusing. I myself, a veteran Zephyr developer, was confused
by this parameter when looking at it recently.
All in-tree uses of the function have been adapted.

The added cellular modem driver is a naive driver, which
shall serve as a template for implementing tailored
drivers for modems like the UBLOX-R4. It uses only
generic at commands, described in 3gpp, and protocols,
like CMUX and PPP.
A binding for the BG95 has been added, which replaces
the quectel,bg9x. This is neccesary since the BG95 does
not have a usable reset pin, the reset and powerkey are
internally connected to each other.
