There appears to be a possible use after free with vdec_close().
The firmware will add buffer release work to the work queue through
HFI callbacks as a normal part of decoding. Randomly closing the
decoder device from userspace during normal decoding can incur
a read after free for inst.
Fix it by cancelling the work in vdec_close.

Core dump is generated whenever there is system error reported
by firmware. Right now, multiple such dumps are generated if
recovery fails in first attempt, since the sys error handler is
invoked again for every failed recovery.
To avoid it, add conditional check to generate core dump only
once during every system error notification from firmware.

Support for FM radio is therefore missing. The device contains:

Video node formats have direct dependency by the sub-device pad formats.
Remove dependency for SoC version and move format definitions in device
which creates video node.
This commit attaches a struct to the VFE resources that holds format
description, so it is much easier to assign them to the video node.
No need to use a switch-case.
NOTE: The mbus_bpp is used to calculate the clock rates and is different
from bpp which is the bits per pixel written to memory. We need to keep
both values to not break the calcualtions.

Instead of using hardwired video loopback limited to a single vivid
instance, use the new 'Connected To' controls to only loopback if an
HDMI or S-Video input is connected to another output, which can be
in another vivid instance. Effectively this emulates connecting and
disconnecting an HDMI/S-Video cable.
The Loop Video control is dropped since it has now been replaced by
the new 'Connected To' controls. The Display Present has also been
dropped since it no longer fits.

The video loopback functionality in vivid is very crude. What we really
want is to be able to emulate connecting an HDMI or S-Video input to
an HDMI or S-Video output, and the input and output can be in different
vivid instances.
Effectively this emulates what happens when you physically connect an
HDMI or S-Video cable between two devices.
In particular, this makes prototyping with vivid much more realistic.
This patch creates a menu control for each HDMI or S-Video input. The
menu control starts with "Test Pattern Generator" and "None" (i.e.
disconnected). After that up to 62 HDMI or S-Video outputs are listed
that you can connect the input to.
If there are more than 62 HDMI or S-Video outputs, then those will not
be included in the menu (currently menucontrols have max 64 entries).
If an input is connected to an output, then all other 'Connected To'
controls are updated to exclude that output to avoid having multiple
inputs connected to the same output.

When setting the EDID it would attempt to update two controls

.s_stream() operation with the v4l2_subdev_enable_streams() and
