Fail compilation when incorrect configuration is detected, i.e. when
SHELL_BACKEND_SERIAL_CHECK_DTR is set but UART_LINE_CTRL is not set.
Use periodic timer to wait for DTR instead of waiting in uart callback
to prevent blocking caller workqueue and/or sleeping in ISR.
DTR check was only ever supported with interrupt driven backend so add
appropriate depends on to Kconfig.

sending data")

Many device pointers are initialized at compile and never changed. This
means that the device pointer can be constified (immutable).
Automated using:
```
perl -i -pe 's/const struct device \*(?!const)(.*)= DEVICE/const struct
device *const $1= DEVICE/g' **/*.c
```

In order to bring consistency in-tree, migrate all subsystems code to
the new prefix <zephyr/...>. Note that the conversion has been scripted,
refer to zephyrproject-rtos#45388 for more details.
