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.

As rx_buf & tx_buf are defined with a NETUSB_MTU size, this cause
that the frames over 1500 bytes can not be received and are discarded.
Secondly, as fragmentation is not supported (for UDP and TCP datagram),
increase NETUSB_MTU to the maximum possible ethernet frame size :1522

Move ECM functionality from netusb to function_ecm making defines not
needed in many cases.

usb_dc_status_callback() parameters are interface or configuration
numbers and should be const.

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.

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.

netusb endpoint config is specific to the function (ECM, RNDIS, EEM..).
Move this config to the function interface.

Move class_handler and send_pkt to netusb function interface.
This makes netusb 'function' agnostic.
