a fixed mapping between endpint addresses and the supported

The URB data processing for DVB bulk transfers is very similar to
what is done with isoc transfers, so create a common function that
works with both transfer types based on the existing isoc function.
This patch has been compilation tested only, because I don't have

em28xx_copy_video uses a wrong offset for the target buffer
when copying the data from an USB isoc packet. This happens
only for the second and all following lines in the packet.

This patch series adds support for USB bulk transfers to the em28xx driver.
