Now that we've disassociated IP steppings from revision ID, I don't
think we should use stepping terminology for the constant inputs to the
array anymore.  The terms you're using seem to roughly correspond to
what the bspec refers to as "SOC stepping" but even that's not terribly
accurate since, for example, PCI revision ID 0xC is used for SoC
steppings C0, C1, D0, and H0.  I'd just use the exact numeric PCI ID as
documented in the bspec to remove any ambiguity:

        const struct i915_rev_steppings adls_revid_step_tbl[] = {
                [0x0] = { .gt_stepping = STEP_A0, .disp_stepping = STEP_A0 },
                [0x1] = { .gt_stepping = STEP_A0, .disp_stepping = STEP_A2 },
                [0x4] = { .gt_stepping = STEP_B0, .disp_stepping = STEP_B0 },
                [0x8] = { .gt_stepping = STEP_C0, .disp_stepping = STEP_B0 },
                [0xC] = { .gt_stepping = STEP_D0, .disp_stepping = STEP_C0 },
        };

That also matches how we're indexing into the TGL arrays.
