Rename EM28XX_NUM_PACKETS to EM28XX_NUM_ISOC_PACKETS and
EM28XX_DVB_MAX_PACKETS to EM28XX_DVB_NUM_ISOC_PACKETS to
clarify that these values are used only for isoc usb transfers.
Also use the term num_packets instead of max_packets, as this
is how these values are used and called in struct urb.
It will be used for USB bulk transfers, too.

The URB data processing for 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.

The current enpoint logic ignores all bulk endpoints and uses
a fixed mapping between endpint addresses and the supported
data stream types (analog/audio/DVB):
Ep 0x82, isoc = analog
Ep 0x83, isoc = audio
Ep 0x84, isoc = DVB
Now that the code can also do bulk transfers, the endpoint
logic
em28xx_urb_data_copy_vbi is actually an extended version of
em28xx_urb_data_copy. With some minor fixes applied, it can be
used for non-vbi-devices, too, without any performance impacts.
Tested with a non-VBI device only.

Typical video devices like camera sensors require an external clock source.
Many such devices cannot even access their hardware registers without a
