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

unsigned int is enough as the clock is expressed in kHz. To make it
extra clear, you could also name the field max_mode_clock_khz.
