Filter out status register against the interrupts' mask.
Some events are being reported via DP status register, even if
corresponding interrupts have been disabled. One instance of such event
leads to generation of VBLANK when the driver is in DRM bridge mode,
which in turn results in NULL pointer dereferencing. We should avoid
processing such events in an interrupt handler context.
This problem is less noticeable when the driver operates in DMA mode, as
in this case we have DRM CRTC object instantiated and DRM framework
simply discards unwanted VBLANKs in drm_handle_vblank().

ZynqMP DPSUB supports 2 input modes: DMA based and live video.
In the first mode, the driver implements CRTC and DP encoder DRM bridge
to model the complete display pipeline. In this case, DRM bridge is
being directly instantiated within the driver, not using any bridge
discovery mechanisms.
In the live video input mode video signal is generated by FPGA fabric
and passed into DPSUB over the connected bus. In this mode driver
exposes the DP encoder as a DRM bridge, expecting external CRTC to
discover it via drm_of_find_panel_or_bridge() or a similar call. This
discovery relies on drm_bridge.of_node being properly set.
Assign device OF node to the bridge prior to registering it. This will
make said bridge discoverable by an external CRTC driver.

DISPLAY_FLAGS_SYNC_POSEDGE is missing in the flags on the default
timings. When overriding the default mode with one described in the
device tree, the mode does not get acked because of this missing flag.
Moreover since the panel is driven by the positive edge it makes sense
to add it here.

This IP block is found in the HDMI subsystem of the i.MX8MP SoC. It has a
full timing generator and can switch between different video sources. On
the i.MX8MP however the only supported source is the LCDIF. The block
just needs to be powered up and told about the polarity of the video
sync signals to act in bypass mode.
