The ADV7533 supports a maximum pixel clock of 80MHz whereas it is 148.5MHz
for ADV7535. Add max_mode_clock_khz variable to struct adv7511_chip_info to
handle this difference.

* Added Rb tag from Adam and Laurent
* Added tested by tag from Adam.
* Replaced max_mode_clock->max_mode_clock_khz in struct adv7511_chip_info
* Replaced variable type from unsigned int->unsigned long.
