EDID parser assigns temporary Video Identification Codes (VIC) for
all non-standard resolutions when parsing a sink's EDID. These
VICs can be reused for a subsequent connection for different
resolutions. In the current implementation of the Display Port (DP)
driver, a resolution change is detected whenever a new VIC is used.
However, when switching between two non-standard resolutions spanning
connections to two different sinks, it is possible to have the same
VIC assigned for the two resolutions. This can result in abnormal
behavior. Fix this by resetting the video identification code and panel
information to reset value every time we get an HPD for disconnect.

It is observed that some PD-capable sink devices have a
longer start-up delay before responding to the Source
Capabilities message with a Request. Since it is PD capable
we'd like to wait until after entering PE_SRC_Ready and VDM
Discovery to start USB host mode. Accommodate these devices by
increasing the number of failed attempts of sending the message
from 5 to 10 before treating it as a non-PD device and starting
host mode.

This reverts commit 85cc38fca2 ("usb: pd: Add support to set the
maximum speed via extcon") which unnecessarily restricted starting
USB host mode to high-speed only. Relax this so that USB host can
start in SuperSpeed when DFP mode is entered.
However, the only exception is if DisplayPort mode is discovered,
we need to drop down to high-speed only due to current hardware
limitations. This is handled during the VDM discovery stage.
Also use this opportunity to refactor all extcon_set_state_() calls
to helper functions that start/stop USB host/peripheral modes.

The 's' flag is supposed to indicate that a softirq is running. This
can be detected by testing the preempt_count with SOFTIRQ_OFFSET.
The current code tests the preempt_count with SOFTIRQ_MASK, which
would be true even when softirqs are disabled but not serving a
softirq.
