    i915/gem_ctx_isolation: Bump support for Tigerlake

    There's very little variation in non-privileged registers for Tigerlake,
    so we can mostly inherit the set from gen11. There is no whitelist at
    present, so we do not need to add any special registers.

    v2: Add COMMON_SLICE_CHICKEN2, GEN9_SLICE_COMMON_ECO_CHICKEN1 and a
    variety of huc readonly status registers.
