drm/i915: Parse and set stepping for platforms with GMD
Expand the current stepping convention to accommodate the GMD
stepping info. Typically GMD step maps to letter stepping
by "A + step %4" and number to "A + step /4" i.e, GMD step
0 maps to STEP_A0, 1 to _A1, 2 to _A2, 3 to _A3, 4 to STEP_B0...
Future platforms might break this formulae and may require a table
mapping to decode GMD step compatible with the convention.
v2:
- Pass the updated ip version structure
v3:
- Skip using GMD to step table(MattR)
