[media] au0828: fix i2c clock speed for DViCO FusionHDTV7
DViCO FusionHDTV7 device that use au0828 can fail to communicate with xc5000 using i2c interface because of high i2c clock speed - i2c clock stretching bug. It causes to fail xc5000 firmware loading normally at the current driver. Already this problem fixed as changing to low i2c clock speed at HVR-950q device, also DViCO FusionHDTV7 device can solve it as using low i2c clock speed - 20KHz.
