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.
