drm/panel: panel-simple: Make panel_simple_probe return its panel

In order to fix the regession introduced by commit de04bb0089a9
("drm/panel/panel-simple: Use the new allocation in place of
devm_kzalloc()"), we need to move the panel_desc lookup into the common
panel_simple_probe() function.

There's two callers for that function, the probe implementations of the
platform and MIPI-DSI drivers panel-simple implements.

The MIPI-DSI driver's probe will need to access the current panel_desc
to initialize properly, which won't be possible anymore if we make that
lookup in panel_simple_probe().

However, we can make panel_simple_probe() return the initialized
panel_simple structure it allocated, which will contain a pointer to the
associated panel_desc in its desc field.

This doesn't fix de04bb0089a9 ("drm/panel/panel-simple: Use the new
allocation in place of devm_kzalloc()") still, but makes progress
towards that goal.
