media: cx23885: Override 888 ImpactVCBe crystal frequency
Hauppauge produced a revision of ImpactVCBe using an 888, with a 25MHz crystal, instead of using the default third overtone 50Mhz crystal. This overrides that frequency so that the cx25840 is properly configured. Without the proper crystal setup the cx25840 cannot load the firmware or decode video.
