[PATCH] dvb: usb: add supprt for WideView WT-220U

Add support and rewrote some parts with the help of vendor information
(Thanks to Steve Chang from WideView, Inc.):

o added support for the WT-220U (Pensize DVB-T receiver)
o corrected byte order for unc,ber and the pid filter
o corrected number of pids that can be fetched at the same time.
o added some comments in Kconfig-file
o added USB IDs for the WT-220U
