Like for render-nodes, there is no point in maintaining the master concept
for control nodes, so set the struct drm_file::master pointer to NULL.

At the same time, make sure DRM_MASTER | DRM_CONTROL_ALLOW ioctls are always
allowed when called through the control node. Previously the caller also
needed to be master.

v2: Adapt to refactoring of ioctl permission check.
v3: Formatting of logical expression. Use drm_is_control_client() instead of
    drm_is_control().

Right now a debug message looks like:

  [drm:drm_ioctl], pid=860, dev=0xe200, auth=1, DRM_IOCTL_MODE_GETCRTC

That first comma looks weird as we already have ']' as a separator.
Remove it.

If anyone sees this commit message and also thinks that auth=1 isn't the
most useful info to have here, let's just say I'd happily review a patch
removing it. If I don't get annoyed enough to submit a patch, that is.

In the logging code, we are currently checking is we need to output in
drm_ut_debug_printk(). This is too late. The problem is that when we write
something like:

    DRM_DEBUG_DRIVER("ELD on [CONNECTOR:%d:%s], [ENCODER:%d:%s]\n",
                     connector->base.id,
                     drm_get_connector_name(connector),
                     connector->encoder->base.id,
                     drm_get_encoder_name(connector->encoder));

We start by evaluating the arguments (so call drm_get_connector_name() and
drm_get_connector_name()) before ending up in drm_ut_debug_printk() which will
then does nothing.

This means we execute a lot of instructions (drm_get_connector_name(), in turn,
calls snprintf() for example) to happily discard them in the normal case,
drm.debug=0.

So, let's put the test on drm_debug earlier, in the macros themselves.
Sprinkle an unlikely() as well for good measure.

The recently added PTN3460 device driver uses interfaces that
are provided by the KMS helper infrastructure, so we should
explicitly select that to avoid this linker error:

ERROR: "drm_helper_probe_single_connector_modes" [drivers/gpu/drm/bridge/ptn3460.ko] undefined!
ERROR: "drm_helper_connector_dpms" [drivers/gpu/drm/bridge/ptn3460.ko] undefined!

We have to drop the I2C dependency to avoid a circular dependency
chain, but that's ok because DRM already selects I2C.

*hpos horizontal scanout position doesn't need to be corrected
to count the pixels between hactive end and htotal negative.
That is only needed for *vpos to count lines until end of
vblank for the vblank timestamping.

Use hpos as is without correction.

Removes occassional spikes in timestamps of up to 1 scanline
duration, thereby improves accuracy to about +/- 2 usecs instead
of +/- 12 usecs, wrt. true onset time as measured with high
precision equipment on NV-A5.
