Alexander Usyskin	a0776c214d	mei: gsc_proxy: match component when GSC is on different bus ... On Arrow Lake S systems, MEI is no longer strictly connected to bus 0, while graphics remain exclusively on bus 0. Adapt the component matching logic to accommodate this change: Original behavior: Required both MEI and graphics to be on the same bus 0. New behavior: Only enforces graphics to be on bus 0 (integrated), allowing MEI to reside on any bus. This ensures compatibility with Arrow Lake S and maintains functionality for the legacy systems.
