Tomasz Bursztyka e18fcbba5a device: Const-ify all device driver instance pointers 
Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.

A coccinelle rule is used for this:

@r_const_dev_1
  disable optional_qualifier
@
@@
-struct device *
+const struct device *

@r_const_dev_2
 disable optional_qualifier
@
@@
-struct device * const
+const struct device *

Fixes #27399

Tomasz Bursztyka 7d1af02410 uart: Fix uart_irq_callback_set usage 
It was already using uart_irq_callback_user_data_set below, now it also
uses uart_irq_callback_user_data_t as callback type, so let's normalize
the callbacks.

Fixes #26923

Jukka Rissanen 775dcb222e modem: gsm: Initialize the modem UART separately 
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.

Michael Scott d56a05f7a7 drivers: modem: interface: introduce UART interface driver layer 
The UART-based modem interface layer implements the modem context
interface for Zephyr's UART APIs.  This driver closely resembles
the existing modem receiver, but conforming to the modem interface
agreements.

Example modem driver setup code looks like this:

/* create modem context object */
static struct modem_context mctx;

/* create uart interface data object and buffers */
static struct modem_iface_uart_data iface_data;
static u8_t iface_isr_buf[MDM_RECV_BUF_SIZE];
static u8_t iface_rb_buf[MDM_MAX_DATA_LENGTH];

iface_data.isr_buf = &iface_isr_buf[0];
iface_data.isr_buf_len = sizeof(iface_isr_buf);
iface_data.rx_rb_buf = &iface_rb_buf[0];
iface_data.rx_rb_buf_len = sizeof(iface_rb_buf);
ret = modem_iface_uart_init(&mctx.iface, &iface_data,
			    UART_DEV_NAME);
