From: Akeem G Abodunrin <akeem.g.abodun...@intel.com>
New LRI register offsets were introduced for DG2, this patch adds
those extra registers, and create new register table for setting offsets
to compare with HW generated context image - especially for gt_lrc test.
Also updates general purpose register with scratch offset for DG2, in
order to use it for live_lrc_fixed selftest.
