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 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.
