video: da8xx-fb: driver enhance to support TI am335x SoC

Changes in v3:
Address the patch authorship requirements
Pull out the DT changes into a separate series
Fix an issue where FB_MODE_HELPERS was not included in build
but is a dependency.
Include the devm_ changes and error reporting that Prabhakar Lad
had pushed a patch for,
A few more cosmetic changes
Add a patch to remove the use on inline from a number of functions

Changes in v2:
Addressing review comments from Tomi Valkeinen:
Dropped readl/writel patch as it is not necessary for non-cached,
non-buffered memory.
Many cosmetic changes to make code easier to understand

This is primarily a resend of a series of patches that were original submitted to linux-fbdev back in January of 2013 for 3.8 by Afzal Mohammed. I have rebased them on 3.10 and also made sure they apply cleanly to the 'for-next' branch of linux-fbdev git. The patches enable use of the current mainline da8xx-fb driver on the TI AM335x SOC along with some bug fixes and cleanup.

The original patch series can be found here:
