For platforms that can't do native 4:2:0 outout we may still be
able to do it by getting the DP->HDMI protocol converter to
perform the 4:4:4->4:2:0 downsamling for us. In this case we
have to configure our hardware to output YCbCr 4:4:4, which we've
already hooked up so all we need to do is flip the switch.

Account for the TMDS clock limits declared by the DFP
when determining what color depth we're going to use.
v2: Drop the reference to DP++ dongle since it's not handled here

The SDVO/HDMI port register limited color range bit can only be used
with TMDS encoding and not SDVO encoding, ie. to be used only when
using the port as a HDMI port as opposed to a SDVO port. The SDVO
spec does have a note that some GMCHs might allow that, but gen4
bspec vehemently disagrees. I suppose on ILK+ it might work since
the color range handling is on the CPU side rather than on the PCH
side, so there is no clear linkage between the TMDS vs. SDVO
encoding and color range. Alas, I have no hardware to test that
theory.
To implement limited color range support for SDVO->HDMI we need to
ask the SDVO device to do the range compression. Do so, but first
check if the device even supports the colorimetry selection.

We have a mix of dport, intel_dport, intel_dig_port and dig_port to
reference a intel_digital_port struct. Numbers are around
5 intel_dport
36 dport
479 intel_dig_port
352 dig_port
Since we already removed the intel_ prefix from most of our other
structs, do the same here and prefer dig_port.
v2: rename everything in i915, not just a few display sources and

The #include has been splattered all over the place, but there are
precious few places, all .c files, that actually need it.

Lots of enc_to_foo(&encoder->base) around. Simplify by passing
in the intel_encoder instead.

We dont need the definition of the enum port outside I915, anymore.
Hence move enum port definition into I915 driver itself.
v2:
intel_display.h is included in intel_hdcp.h
v3:
enum port is declared in headers.
v4:
commit msg is rephrased.
v5:
copyright year is updated [Tomas]

Add a new subdirectory for display code, and start off by moving
modesetting output/encoder code. Judging by the include changes, this is
a surprisingly clean operation.
v2:
- move intel_sdvo_regs.h too
- use tabs for Makefile file lists and sort them
