Replace 'adv->type'->'info->type' by moving variable 'type' from struct adv7511 to struct adv7511_chip_info and add adv7511_chip_info as device data for both OF and ID tables instead of the device type. Simplify the probe() by replacing of_device_get_match_data() and ID lookup for retrieving match data with i2c_get_match_data().

Some monitors do this when they wake up from standby or are enabled. When the HPD goes low the adv7511 is reset and the outputs are disabled which might cause the monitor to go to standby again. To avoid this we ignore the HPD pin for the first few seconds after enabling the output. On the other hand, adv7535 require to enable HPD Override bit for proper HPD. Add hpd_override_enable variable to struct adv7511_chip_info to handle this scenario.
