It has been observed that using a CMUX max frame size of 127
causes FCS errors; smaller or larger works. This commit sets the max
frame size to the modem's default value.

U-Blox LARA-R6 was added to modem_cellular, and an additional state
was introduced where the UART baudrate is changed if the modem supports
it

Add two DLCI channels to the cellular modem driver, and expose
them using the modem pipelink module.

The new modem_cellular driver had support for the deprecated
generic zephyr,gsm-ppp dts compatible for backwards compatibility.
zephyr,gsm-ppp is being removed, and as such, modem_cellular.c
no longer needs to support it.

Adds the necessary defines with init, dial and periodic chat scripts to
support the Sequans GM02S Modem.
Modification to cxreg handler to process GM02S +CEREG response.

The nRF91 series devices, when running the Serial LTE Modem (SLM)
application starting with nRF Connect SDK 2.6.0, can now be used as
standalone modems via the generic modem_cellular driver.
A configuration to run the cellular_modem sample on the nRF9160 DK
(plugged in to another nRF91 series device running SLM) is provided.

U-blox SARA-R4 already exists but the behavior is different,
requiring a separate driver instance. For instance, R5 autostarts,
so this commit also adds support for skipping power on pulse.

Some modems or networks require PAP authentication for successful
LCP handshake. Tested on U-blox SARA-R5 with zephyr,gsm-ppp.

The init scripts need a missing wait for OK after sending
AT+CGMM and the AT+CMUX command specifies more parameters
than nessesary, and in some cases incorrectly.
This commit adds the missing wait for OK and fixes the AT+CMUX
commands in the init scripts.

Added chat script and initial config to support Telit ME910G1.
Needed to edit power_pulse pin timing in accordance to datasheet.

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.
