Some DRM drivers lacked the drm_panel.h include to use drm_panel_put()
after the commit b71a623598d3 ("drm/panel: of_drm_find_panel() return a counted reference").

Callers of of_drm_find_panel() and drm_of_find_panel_or_bridge()
receive a pointer with no reference held, creating a window where
the panel device can be unregistered and freed between the lookup
and first use (e.g., drm_panel_prepare()).

Fix the lookup function by acquiring a reference with drm_panel_get()
before returning, under panel_lock. Callers are now responsible for
calling drm_panel_put() when they no longer need the pointer.

For bridge drivers that immediately wrap the panel in a panel_bridge
(which acquires its own reference), release the lookup reference right
after the bridge creation call.

For analogix-anx6345, which stores the panel for direct use, release
the reference in the i2c remove path.

For platform drivers using analogix_dp_core with a component lifecycle
(exynos_dp, rockchip analogix_dp), release the lookup reference in the
platform remove() function. The panel_bridge created during bind() holds
a separate reference that devm cleanup releases after remove() returns.

Also fix devm_drm_of_get_bridge() and drmm_of_get_bridge() in
bridge/panel.c itself, update a second batch of drivers calling
of_drm_find_panel() or drm_of_find_panel_or_bridge() to release the
lookup reference after wrapping the panel in a bridge, and handle the
cases where a panel is found but cannot be used, dropping the reference
immediately in those paths.

Replace the #include of <linux/mod_devicetable.h> by the more specific
<linux/device-id/*.h> where applicable. For most cases the include
can be dropped completely, only a few drivers need one or two headers
added.

lcdif_attach_bridge() uses dev_err_probe() on all its error returns to
store a specific deferral message.

However its caller lcdif_load() calls dev_err_probe() again on error,
overwriting the specific deferral messages with a unique, unavoidably
generic, message.

Make the specific deferral message visible by using a plain 'return ret' on
the caller.

It is necessary to wait for the full frame to finish streaming
through the DMA engine before we can safely disable it by removing
the DISP_PARA_DISP_ON bit. Disabling it in-flight can leave the
hardware confused and unable to resume streaming for the next frame.

This causes the FIFO underrun and empty status bits to be set and
a single solid color to be shown on the display, coming from one of
the pixels of the previous frame. The issue occurs sporadically when
a new mode is set, which triggers the crtc disable and enable paths.

Setting the shadow load bit and waiting for it to be cleared by the
DMA engine allows waiting for completion.

The NXP BSP driver addresses this issue with a hardcoded 25 ms sleep.

There is an undocumented bit used in the NXP BSP to clear the FIFO
systematically at vsync. In normal operation, the FIFO should already
be empty but it doesn't hurt to add it as an extra safety measure.
