drm/i915: Reorganize display pipe register accesses

RFCv2: Reorganize array indexing so that full offsets can be used as
is. It makes grepping for registers in i915_reg.h much easier. Also
move offset arrays to intel_device_info.

v1: Fixed offsets for VLV, proper eDP handling

v2: Fixed BCLRPAT, PIPESRC, PIPECONF and DSP* macros.

v3: Added EDP pipe comment, removed redundant offset arrays for
    MSA_MISC and DDI_FUNC_CTL.

v4: Rename patch and report object size increase.

v5: Change location of commas, add PIPE_EDP into enum pipe

v6: Insert PIPE_EDP_OFFSET into pipe offset array

v7: Set I915_MAX_PIPES back to 3, change more registers accessors
    to use the new macros, get rid of _PIPE_INC and add dev_priv
    as a parameter where required by the new macros.

Upcoming hardware will not have the various display pipe register
ranges evenly spaced in memory. Change register address calculations
into array lookups.

Tested on SNB, VLV, IVB, Gen2 and HSW w/eDP.

I left the UMS cruft untouched.

Size differences:
