RFC TI LCDC DRM driver

Updated version of DRM driver for TI LCD Controller. Since the initial version of the patch, which only supported TFP410 DVI output, I've added an output driver for LCD panels (for example, LCD3 or LCD7 cape for the beagle-bone), and initial support for HDMI output via NXP TDA19988 HDMI encoder (via i2c encoder-slave output driver).

At this point, I think the basic lcdc drm driver plus TFP410 DVI output (first patch) is in reasonable shape (barring potential rename, if lcdc is too generic of a name... but I was not feeling creative enough yet to pick a new name).

The second patch, adding LCD panel support, still needs backlight support. And the DT bindings for panel parameters should probably be made more generic. But I guess someone should have some opinions on that so I figured it would be good to send as an RFC in it's current form and hear other's opinions.

The remaining two patches, adding support for HDMI output via NXP TDA998x i2c encoder are fairly preliminary, but basically working (for some definitions of working). At this point, there is only basic DVI output support. Audio, HDCP, etc, can come later.
