The DDC scl high and low times were set to the minimum values
from the i2c specification, but the i2c specification takes into
account the rise time and fall time to calculate the frequency.
To pass HDMI certification DDC can not exceed 100kHz therefore in
a system where the rise times and fall times are negligible the high
and low times for scl need to be 10us.

The AVI infoframe R0-R3 in the 2nd data byte represents the
Active Format Aspect Ratio. It is four bits long not two bits.
This fixes that mask used to extract the bits before writing the
bits to the hardware registers.

Add the missing bits for interlace:
* Set VBLANK_OSC if the videomode's vblank is fractional
* Halve the vertical timings for interlace
* Double the horizontal timings for double-pixel mode
* Set FC_PRCONF properly for double-pixel mode

The HDMI driver copies the timing values one by one. Instead we can just
copy the whole struct.

For some reason the HDMI FC's HSW value is programmed to hsw-1. There's
no indication in the documentation that this would be correct, and no
other blanking value needs -1 either.
So remove the -1.

Now that omapfb has its own copy of omapdss and display drivers, we can
move omapdss and display drivers which omapdrm uses to omapdrm's
directory.
We also need to change the main drm Makefile so that omapdrm directory
is always entered, because omapdss has a file that can't be built as a
module.
