Subject: [PATCH 4/6] ARM: davinci: dm355: enable fbdev driver

From: Lad, Prabhakar <prabhakar.csengg@...il.com>

This patch enables fbdev driver by creating fbdev device and register it.
Alongside renames 'vpfe_capture_dma_mask' to 'dm355_video_dma_mask' for better
clarity since it was reused by capture and diplay aswell.
