[RESEND PATCH] drm/tilcdc: fix raster control register setting

From: Dario Binacchi
Date: Tue Feb 16 2021 - 15:18:49 EST


The fdd property of the tilcdc_panel_info structure must set the reqdly
bit field (bit 12 to 19) of the raster control register. The previous
statement set the least significant bit instead.
