Set off-on-delay-us to 500000 us for pp3300_mipibrdg to make sure it
complies with the panel sequence. Explicit configuration on the
regulator node is required because mt8192-asurada uses the same power
supply for the panel and the anx7625 DP bridge. So powering on/off the
DP bridge could break the power sequence requirement for the panel.
