Fix the electrical compliance test sequence by bypassing
the link training whenever there is a request for a new
PHY test pattern. Link training triggers the sending of
training patterns which might differ from the requested
PHY test pattern. Furthermore, handle the state DP
transitions for power on/off since there is no userspace
interaction for the electrical compliance tests.

A sink uses the HPD IRQ signal to notify the source of for any
link maintenance, link tests and HDCP related messages. Current
implementation tears down the entire display pipeline when this
signal is received. This may not be necessary as it would be
needed to keep the DP interface enabled while any kind of link
maintenance is performed. Fix this and ensure that when handling
of the HPD IRQ is complete, re-establish the display pipeline.

Display Port (DP) controller has the ability to calculate CRC values
for every frame. In addition, most DP sinks also have the capability
to calculate per frame CRC values. Add support to enable/disable
calculation of per-frame CRC values for both the DP controller and
the DP sink. Add support to read the computed CRC values via a new
sysfs node. See below for usage instructions:
To enable/disable per frame CRC calculation:
* echo "ctl_cr_en=[0/1]" > /sys/class/graphics/<fbi>/frame_crc
* echo "sink_cr_en=[0/1]" > /sys/class/graphics/<fbi>/frame_crc
To read computed CRC values:
* cat /sys/class/graphics/<fbi>/frame_crc

Resolutions listed in the Detailed Timing Descriptor (DTD) have
detailed information about all the timings. Current implementation
attempts to match the parsed resolution with the resolution database
based on just the Video Information Code (VIC). This can potentially
overlook mismatches in certain parameters such as refresh rates and
can cause unintended results. Fix this by always adding the resolutions
parsed from the DTDs to the reserved timing list.

Current implementation of the EDID parser always ensures that
VGA resolution (640x480) is added to the list of supported modes.
However, this should really be done by the client of the parser
based on their policies. This will avoid usecases where the EDID
parser would report the VGA resolution as supported even if it
was not listed in the sink's EDID.

Current implementation utilizes a simple event queue to handle
some of the tasks when setting up or tearing down a display port
session. This is currently achieved using a workqueue and assumes
that there can be at most one unhandled event outstanding. This
may not be valid and can result certain events being skipped.
Refactor this by handling the events in a new event thread.

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.

If read function is waiting for interrupt and after that
NFCC goes to recovery, MW will call ioctl (0) and ioctl (1),
In ioctl (0) call we are disabling interrupt so read function
was waiting for interrupt and ioctl call has disabled interrupt,
now there is no possibility interrupt will be enabled again
because only read function enables the interrupt.
Enabled interrupt in ioctl (1) so that we can receive data
