V4L/DVB (5574): Pvrusb2: Improve handling of PAL-60 video standard
This patch originated with Servaas Vandenberghe <vdb128@picaros.org> and has been further developed a bit (to preserve saa7115 behavior). These changes allow for correct operation of PAL-60 video (Servaas tested this against a PAL-B/G tuner with the video standard overridden as a module option).
