Subject: [PATCH 31/32] drm/mcde: use the DSI host pointer in mcde_dsi_irq

mcde_dsi_irq() takes a struct mipi_dsi_device which it uses solely to get
the struct mipi_dsi_host pointer.

We want to get rid of mipi_dsi_device pointers in host drivers, so use
directly the struct dsi_host pointer which is now stored in struct
mcde.
