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).

Remove all CONFIG_*_EP_ADDR options but keep the default
values for it, as they are necessary to find ep_addr in
usb_ep_cfg_data associated with bEndpointAddress in
interface descriptor.

Adapt functions for new composite interface.
Assign bInterfaceNumber and similar variables of a Interface
default values, these should be valid values for non-composite
configuration. For the case of the composite configuration,
these variables must be set by the interface configuration
function (interface_config) accordingly.

This patch changes all class functions so that the endpoint
address will be retrieved from the usb_ep_cfg_data at runtime.

This patch moves the descriptor parts to related class
and function drivers and extends the usb_fix_descriptor
function so that the wTotalLength and bNumInterfaces
are corrected before enumeration.

As per uart_pipe.c, irq_is_pending should only return true if any
*unmasked* interrupts are pending.
The device_get_binding() code only checks devices that have an API.
Set the API at compile time so that other devices can refer to the CDC
ACM driver.
usb_write() may return EBUSY if the endpoint is full. Propagate this
for future use.

Composite multifunction USB devices should be able to know about
configuration change, implement it through existing callback.

Sometime it is observed on the Arduino 101 that when we write more than
4 bytes into TX USB Endpoint, first 4 bytes are getting repeated
(frequency of occurrence ~1/3000).
This patch does following :-
1. In sample application "cdc_acm", it adds capability to
handle partial transfer data incase data is transferred partially
if exceeds maximum data transfer size.
2. It restricts write of more than 4 bytes into TX USB Endpoint.
This is work around to avoid issue occarance.

Move logging out of misc/ to its own subsystem. Anything related to

instead of the generic location in misc/ which is overcrowded with
