[PATCH 4/8] thunderbolt: debugfs: Replace "both lanes" with "all lanes"

[Mika Westerberg <mika.westerberg@linux.intel.com>]

From: Aapo Vienamo <aapo.vienamo@iki.fi>

With USB4 Gen 4, the link can be configured into an asymmetric mode,
where there are three receivers and only one transmitter. The USB4
specification also uses the "all lanes" nomenclature instead of "both
lanes".
