fbdev: omapfb: remove unused variable

Removing the default display name left a harmless warning:

fbdev/omap2/omapfb/dss/core.c: In function 'omap_dss_probe':
fbdev/omap2/omapfb/dss/core.c:196:30: error: unused variable 'pdata' [-Werror=unused-variable]

This removes the now-unused variable as well.
