The IRQ callback function of the USB CDC ACM driver can currently be
called from:
- the USB thread when a bulk in or a bulk out interrupt has been
triggered
- the thread calling cdc_acm_irq_rx_enable or cdc_acm_irq_tx_enable when
enabling the interrupt fires an irq (ie if there is data to read or if
there is no pending data to send)
This causes some issues with at least the shell uart backend, as the
IRQ callback function ends up being called twice concurrently in case a
USB driver sends the requested data almost instantaneously. This is the
case for example of the USB nRF driver which uses DMA. In turn this
cause ring_buf_item_get to be called concurrently, leading to data
corruption:

Commit e4c447aac3 ("usb: add SoF event") added support for calling the
status callback with the USB_DC_SOF value for each SoF when
CONFIG_USB_DEVICE_SOF is enabled. The CDC ACM driver saves the latest
received status and compares it USB_DC_CONFIGURED to decide if it can
send data to the host. This therefore doesn't work any more when the
status callback is called regulary with USB_DC_SOF.
Fix that by ignoring USB_DC_SOF when saving the latest received status.

The CDC ACM driver has to emulate the TX and RX interrupts from the USB
ones. However it does not correctly emulate them as "TX buffer empty"
and "RX buffer not empty" interrupts.
For "TX buffer empty" interrupt:
- Reading the interrupt status should not clear the interrupt
- Enabling the interrupt should fire an interrupt if the TX buffer is
empty
- An interrupt should be triggered when the USB device get configured
For "RX buffer not empty" interrupt:
- Reading the interrupt status should not clear the interrupt
- Enabling the interrupt should fire an interrupt if the RX buffer is
not empty
This make the a console on the USB CDC ACM port usable for the shell
and the logs.

Zephyr UART drivers offer very low-level functionality. Oftentimes,
it would be useful to provide higher-level wrappers around UART
device which would offer additional functionality. However, UART
driver irq callback routine receives just a pointer to (low-level)
UART device, and it's not possible to get to a wrapper structure
(without introducing expensive external mapping structures). This
is an indirect reason why the current UARt wrappers - uart_pipe,
console - are instantiated statically just for one underlying UART
device and cannot be reused for multiple devices.
Solve this by allowing to pass an arbitrary user data to irq
callback, set by new uart_irq_callback_user_data_set() function.
Existing uart_irq_callback_set() keeps setting a callback which
will receive pointer to the device.
While public API maintains compatibility, drivers themselves need
to be updated to support arbitrary user data storage/passing (as
legacy uart_irq_callback_set() functionality is now implemented in
terms of it).

The device_get_binding() code only checks devices that have an API.

ACM driver.
