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.
