drm/msm: Initialize MDSS irq domain at probe time
Since commit 8f59ee9a570c ("drm/msm/dsi: Adjust probe order"), the
DSI host gets initialized earlier, but this caused unability to probe
the entire stack of components because they all depend on interrupts
coming from the main `mdss` node (mdp5, or dpu1).
To fix this issue, move mdss device initialization (which include irq
domain setup) to msm_mdev_probe() time, as to make sure that the
interrupt controller is available before dsi and/or other components try
to initialize, finally satisfying the dependency.
Fixes: 8f59ee9a570c ("drm/msm/dsi: Adjust probe order")
