Subject: [PATCH 4/5] drm: shmobile: Add missing call to drm_fbdev_generic_setup()

Set up generic fbdev emulation, to enable support for the Linux console.

Use 16 as the preferred depth, as that is a good compromise between
colorfulness and resource utilization, and the default of the fbdev
driver.
