we use the delay 200ms to meet the edp power timing request before, it waste time, so we use the HPD function to detect the edp panel now. In previous version, the hardware may not support the edp HPD function, so in the code it will spend 200ms to detect hpd single, if it don't get the hpd single, it will contiue the edp initialization process, to compatible all of the hardware version.
