In DPTX Controller, when hpd signal is low, the hpd state will
change to unplug immediately. if the low level signal is less
than 2ms, the hpd state will change to plug state and trigger a
hpd irq interrupt.
In some case, driver will detect hpd state to get the plug/unplug
info when a hpd irq is coming. A hpd irq may be regard as a unplug
state. To avoid this issue, it better to wait the hpd state change
to the nest state.

Different hdmi sinks have different compatibility issues.
Many of the solutions are conflicting between different sinks,
So special treatment is needed for different sinks.
Only VSI-related quirks are currently supported, new functions
are gradually supported.
