drm/i915: Rename defines for selection of ddi buffer translation slot
Renaming the HSW-specific macros for ddi buffer translation slot to denote the
slot and not the vswing/pre-emph values as they are platform-dependent.
This patch is based on top of the patch series for renaming the DP training
vswing/pre-emph defines:
http://lists.freedesktop.org/archives/intel-gfx/2014-August/050407.html
v2: Creating single macro with argument for slot number (Damien)
v3: Adding macro for num of translation entries (Damien)
