mei: gsc_proxy: match component when GSC is on different bus

commit a0776c214d47ea4f7aaef138095beaa41cff03ef upstream.

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.
