Use standard NET_ETH_MAX_FRAME_SIZE for frame size calculation. This
changes buffer from 1522 to 1514 + 2 + 4. Remove also magic numbers.

Commit 766101c was a wrong fix as NETUSB_MTU is the actual network MTU.
Instead of using this value in EEM/ECM drivers, a relevant value should
be set for each there.

Since commit b48a8c3247 ("usb: device: Add composite status callback")
the cb_usb_status callback is not called anymore in composite mode. The
cb_usb_status_composite callback is called instead.
This patch updates the EEM driver to use either one or the other
depending on CONFIG_USB_COMPOSITE_DEVICE.

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

This patch prevents eem_read_cb from trying to allocate a lot of memory.
It may happen that EEM payload size is zero, the eem_read_cb then tries
to allocate a buffer which is 0xfffc bytes large and luckily blocks.

Add CDC Ethernet Emulation Model function driver. This usb network
function can be used for ethernet over USB. Ethernet packet are
encapsulated within EEM packets. An EEM pkt contains 2-byte header
and 4-byte sentinel (or crc).
Note that EEM packets can be split across USB packets but shall not
be split across USB transfers.
