ADV7511 does not sometimes accept HPD interrupt correctively.
Flow is below
1: Interrupt detection
2: Interrupt clear(0x72, 0x96 bit7)
3: accept HPD status ((0x72, 0x42 bit6))
When Adv7511 accept HPD status and process interrupt clear ,
HPD status is changed by the timing of interrupt clear.
Last change can not be detected when next interrupt input AV7511.
Are above 1 to 3 flow and setting register correrct ?
