drm/i915/xe2lpd: Read pin assignment from IOM
Starting from display version 20, we need to read the pin assignment
from the IOM TCSS_DDI_STATUS register instead of reading it from the
FIA.
We use the pin assignment to decide the maximum lane count. So, to
support this change, add a new lnl_tc_port_get_max_lane_count() function
that reads from the TCSS_DDI_STATUS register and decides the maximum
lane count based on that.
