[Intel-gfx] [PATCH 10/11] drm/i915: rename sdvox_reg to hdmi_reg on HDMI context

From: Paulo Zanoni <paulo.r.zanoni at intel.com>
Some (but not all) of the HDMI registers can be used to control sDVO,
so these registers have two names. When we're talking about HDMI, we
really should call the HDMI control register "hdmi_reg" instead of
"sdvox_reg". So now "struct intel_hdmi" has a member called "hdmi_reg"
instead of "sdvox_reg".
And don't worry: "struct intel_sdvo" still has a member called
"sdvo_reg".
