[Intel-gfx] [PATCH 12/14] drm/i915: clarify confusion between HDMI and SDVO registers

From: Paulo Zanoni <paulo.r.zanoni at intel.com>
Some HDMI registers can be used for SDVO, so saying "HDMIB" should be
the same as saying "SDVOB" for a given HW generation. This was not
true and led to confusions and even a regression.
Previously we had:
- SDVO{B,C} defined as the Gen3+ resgisters
- HDMI{B,C,D} and PCH_SDVOB defined as the PCH registers
Now we have:
- GEN3_SDVO{B,C} defined as the Gen3+ registers
- GEN4_HDMI{B,C} defined as the Gen4+ registers
- PCH_SDVOB defined as the PCH register
- PCH_HDMI{B,C,D} defined as the PCH registers
So now PCH_SDVOB is the same as PCH_HDMIB and GEN3_SDVOB is the same
as GEN4_HDMIB.
