drm/i915: Refactor sseu helper functions

Move functions to intel_sseu.h and remove inline qualifier.
Additionally, ensure these are all prefixed with intel_sseu_*
to match the convention of other functions in i915.

v2: fix spacing from checkpatch warning
v3: squash helper function changes into a single patch
    break 80 character line to fix checkpatch warning
    move get/set_eus helpers to intel_device_info.c
v4: Remove intel_ prefix from static functions in
    intel_device_info.c and correctly copy changes
    to stride calculation in those functions.
