[PATCH 39/48] drm: omapdrm: dsi: Store the struct device pointer in struct dsi_data

[Laurent Pinchart <laurent.pinchart@xxxxxxxxxxxxxxxx>]

The dsi_data structure stores a pointer to a struct platform_device. The
driver only uses the dev member of the platform device structure. Store
the struct device pointer instead and use it directly.
