This is needed if muxing is enabled in which case we must
change the UART to muxing UART after the AT+CMUX command
has succeed.

Instead of using physical UART to connection to the modem, use
the GSM 07.10 muxing protocol and UART mux driver to create
virtual channels to the modem. This will allow simultaneous
PPP, AT and other type connections to the modem.

Run the int_literal_to_timeout Coccinelle script to fix places where
it is clear that an integer duration is being passed where a timeout
value is required.

Add Kconfig option that allows user to set MCC (Mobile Country
Code). If user does not set it, then automatic operator
registration is used.

Misc fixes / enhancements to the GSM driver:
* set the \r as a line ending character
* make gsm_init() static as there is no need to expose it
* print the gsm context pointer at init
* set buffer allocation timeout to modem context so that it is
not infinite

Instead of using global static variable "gsm" everywhere,
store the context when calling DEVICE_INIT(). Then in the device
init function get the context from the device struct. This way
it is possible to use the same functions for implementing two
gsm modem instances. Currently this is not fully possible because
the context is not passed via uart_pipe API and modem_cmd
callbacks. So some future work would still be needed.
In practice this commit does not change anything, it just makes
it a little bit easier to have two instance of this modem which
might be quite unlikely case. Anyway, the driver now follows the
same style how some other drivers are done like Ethernet etc.

Implement uart_pipe functionality for the modem so that it
