This change just make a little clean to make code more like
drm core expect, move hdp detect code from bridge->enable(),
and place them into connector->detect().

On Rockchip platform, sometimes driver would failed at reading EDID
message, and it's caused by the AUX reply flag wouldn't received under
the 100*10us wait time.
But after expand the wait time a little, the AUX reply flag would be
set, so maybe the wait time is a little critical. Besides the anal
Turn off the panel power in suspend time would help to reduce
power waste.

It may caused a dead lock if we flush the hpd work in bridge disable time.
The normal flow would like:
IN --> DRM IOCTL
1. Acquire crtc_ww_class_mutex (DRM IOCTL)
IN --> analogix_dp_bridge
2. Acquire hpd work lock (Flush hpd work)
3. HPD work already in idle, no need to

This refactor results in a cleaner state machine code and as a result fixed a
bug when packaging a MIDI-USB packet right after a non-conformant MIDI byte
stream.

The print_event_field() and print_event_fields() are to print basic
information of a given field or event without the print format. They'll
be used by dynamic sort keys later.

Fix typo. The branch was also updated.

From: Rameshwar Prasad Sahu
For interrupt controller that doesn't support irq_disable and hardware
with level interrupt, an extra interrupt can be pending. This patch fixes
the issue by setting IRQ_DISABLE_UNLAZY flag for the interrupt line.
