Move the panel/encoder driver compatible-string converter from
arch/arm/mach-omap2/display.c to omapdss driver. That is a more logical
place for it, as it's really an omapdss internal hack.

The code is rewritten to follow the video node graph, starting from
omapdss. This removes the need to have the device compatible-string
database.

This adds a new driver to omapdss for OMAP5 HDMI. However, the new
driver uses common HDMI files which are shared with OMAP4 HDMI driver.

OMAP5 HDMI has a different HDMI core IP compared to OMAP4, but has very
similar PLL and PHY IPs which can be handled with common code.

We'll soon add support for OMAP5 HDMI, which uses some of the same files
as OMAP4 HDMI does.

This patch adds a new config entry "OMAP2_DSS_HDMI_COMMON", which both
OMAP4 and OMAP5 HDMI config entries can select. OMAP2_DSS_HDMI_COMMON
will cause the common HDMI files to be compiled.

The drivers/video directory is a mess. It contains generic video related
files, directories for backlight, console, linux logo, lots of fbdev
device drivers, fbdev framework files.

Make some order into the chaos by creating drivers/video/fbdev
directory, and move all fbdev related files there.

No functionality is changed, although I guess it is possible that some
subtle Makefile build order related issue could be created by this
patch.
