Convert string compares of DT node names to use of_node_name_eq helper
instead. This removes direct access to the node name pointer.

>From above warning one would deduce that the sg segment will overflow
the device's capacity. In reality, the hardware can accommodate larger
sg segments.
So, initialize the max segment size properly to weed out this warning.

Make the core set the reserved fields to zero in
vv4l2_pix_format_mplane.4l2_plane_pix_format,
for _MPLANE queue types.
Moving this to the core avoids having to do so in each

We initially introduced a spin lock to ensure that the VPU registers
are not accessed concurrently between our setup function and IRQ
handler. The V4L2 M2M API ensures that only one decoding job runs at a
time, so the interrupt signaling the end of decoding will not occur
while the next picture is being configured.
Spurious interrupts are taken care of in the handler, by checking that
we have a valid M2M context and a decoding status available before
marking the buffers as done.
In addition, holding a spin lock could be problematic if non-atomic
operations are required in the setup process for future codec support.
As a result, remove the global IRQ spin lock.

Add support for the third loop filter mode
V4L2_MPEG_VIDEO_H264_LOOP_FILTER_MODE_DISABLED_AT_SLICE_BOUNDARY,
and fix V4L2_CID_MPEG_VIDEO_H264_LOOP_FILTER_ALPHA and
V4L2_CID_MPEG_VIDEO_H264_LOOP_FILTER_BETA controls.
The filter offset controls are signed values in the -6 to 6 range and
are stored into the slice header fields slice_alpha_c0_offset_div2 and
slice_beta_offset_div2. The actual filter offsets FilterOffsetA/B are
double their value, in range of -12 to 12.
Rename variables to more closely match the nomenclature in the H.264
specification.

The venus and s5p-mfc drivers add the loop filter alpha/beta offset
controls V4L2_CID_MPEG_VIDEO_H264_LOOP_FILTER_ALPHA/BETA with a range of
-6 to +6, inclusive. This is exactly the range specified for the slice
header fields slice_alpha_c0_offset_div2 and slice_beta_offset_div2,
which store half the actual filter offsets FilterOffsetA/B.
Clarify that this control contains the halved offsets.

Trace points are much more efficient than debug messages for intensive
tracing and could be conveniently enabled / disabled dynamically, hence
let's replace debug messages with the trace points. This also makes
code a bit cleaner.
