Some modems (e.g. Quectel BG95/EG25-G, several SIMCom parts) print
“APP RDY” when the application core is ready. Parse this line and
proceed from AWAIT_POWER_ON immediately, while keeping the existing
startup timeout as a fall-back.

Add optional autostarts boolean to the quectel,bg95 binding and make
MODEM_CELLULAR_DEFINE_INSTANCE() use it through DT_PROP_OR().
Boards that carry a BG95-M3 Mini-PCIe card—or any other variant that
boots at VCC can now declare the property and skip the PWRKEY pulse,
while existing designs continue to behave unchanged.

Quectel BG9x returns only the base model string to AT+CGMR, while
AT+QGMR provides the true firmware build ID, e.g.
AT+CGMR → BG95M3LAR02A03
AT+QGMR → BG95M3LAR02A03_01.204.01.204
Replace CGMR with QGMR in the BG95 init script so that
cellular_get_modem_info(... FW_VERSION ...) reports the complete

Recent changes to net_link_addr structure to not use pointers
have made it necessary to update the modem_cellular driver
to ensure compatibility with the new structure definition.

Add support for the simcom a76xx modem which is similar to the simcom 7080

Fix regression introduced by dormant state, where the
carrier does not get closed when Cellular Modem driver
is suspended.
Signed-off-by: Markus Lassila <markus.lassila@nordicsemi.no>
Previously, it was expected that the modem would immediately
disconnect and close the PPP link, when the network was lost
(+CEREG: 4 is received). Failure to do so, would result in
modem attempting to chat with dlci2 channel, where as cellular
modem driver would drop to dlci1. This would show as dial
script timing out, which would freeze cellular modem driver.
Adding dormant state enables graceful disconnection of PPP-link
when the network is lost. This allows the modems which do
not automatically close with network link loss to close
based on PPP link closure.

Allow configuring MTU for CMUX.
Some AT manual and specification define this as a
frame size. Linux ldattach default to 127 bytes,
3GPP TS 27.010 defaults to 31.
We should limit our CMUX frames to a size that
remote end is capable of handling.
Linux silently drops oversized frames.
Also, remove MODEM_CELLULAR_CMUX_MAX_FRAME_SIZE as
this was only limiting a buffer sizes, and resulted
CMUX frames to be capped to same value.
Use MODEM_CMUX_WORK_BUFFER_SIZE and MODEM_CMUX_MTU instead.
Also rename CONFIG_MODEM_CELLULAR_CHAT_BUFFER_SIZES to
CONFIG_MODEM_CELLULAR_CHAT_BUFFER_SIZE as it is now
only used as a Chat module. DLCI pipes use
CONFIG_MODEM_CMUX_WORK_BUFFER_SIZE.

`+C*REG:` may be received as AT read command answer
or unsolicited notification.
Their syntax differs, and even the overall parameter count varies
depending on what `<n>` is used in the `AT+CEREG=` write command.
To handle all cases properly, check the parameter count and
the presence of the `<tac>` parameter (which is a string and
thus begins with `"`) to figure out what is the position of `<stat>`.

Introduced `MODEM_CELLULAR_DEFINE_INSTANCE` macro to streamline
the definition and initialization of modem cellular instances.
This macro enables passing parameters that vary among modems, including:
`power_pulse_duration_ms`, `reset_pulse_duration_ms`, `startup_time_ms`,
`shutdown_time_ms`, `autostarts`, `init_chat_script`, `dial_chat_script`
and `periodic_chat_script`.
