V4L/DVB (10119): em28xx: fix corrupted XCLK value
Correct problem introduced during the board refactoring where the XCLK frequency would get zero'd out. The sequence of events was as follows: em28xx_pre_card_setup() called em28xx_set_model() em28xx_set_model() would memcpy to dev->board configuration em28xx_pre_card_setup() would set the dev->board.xclk if not set em28xx_pre_card_setup() would set the XCLK register based on dev->board.xclk ... em28xx_card_setup() would call em28xx_set_model() em28xx_set_model() would memcpy to dev->board configuration (clearing out value of dev->board.xclk set in em28xx_pre_card_setup) ... em28xx_audio_analog_set() sets the XCLK register based on dev->board.xclk (which now contains zero) The change sets the default XCLK and I2C Clock fields in the board definition inside of em28xx_set_model() so that subsequent calls do not cause the values to be overwritten.
