drm/i915: add SSC offsets for SBI access

Browse Source 
Different registers are identified by their target id and offset. To
simplify their programming, they are called as <RegisterName><TargetId>.
For example, SSCCTL register accessed through SBI at target id 6 and
offset 0c is called SBI_SSCCTL6.
