dispc_mgr_timings_ok() is a bit confusing how it handles the return
value.
Change the function to just return immediately when a timing is deemed
not valid, making the code much easier to follow.

OMAP2/3 does not support interlace for LCD out. OMAP4+ does, but is not
supported by the driver at the moment.
The driver still accepts interlaced mode for LCD out, causing broken
display output.
This patch makes dispc reject interlace for LCD out.

When omapdss writes to DISPC_POL_FREQ register, it always ORs the bits
with the current contents of the register, never clearing the old ones,
causing wrong signal polarity settings.
As we write all the bits in DISPC_POL_FREQ, we don't need to care about
the current contents of the register. So fix the issue by constructing
new register value from scratch.

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.
