thunderbolt: No need to warn if NHI hop_count != 12 or hop_count != 32
While Intel hardware typically has hop_count (Total Paths in the spec) 12 the USB4 spec allows this to be anything between 1 and 21 so no need to warn about this. Simply log number of paths at debug level. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>
