drm/i915/lnl+/tc: Use the cached max lane count value
commit c5c2b4b3841666be3a45346d0ffa96b4b143504e upstream.
Use the cached max lane count value on LNL+, to account for scenarios
where this value is queried after the HW cleared the corresponding pin
assignment value in the TCSS_DDI_STATUS register after the sink got
disconnected.
For consistency, follow-up changes will use the cached max lane count
value on other platforms as well and will also cache the pin assignment
value in a similar way.
