Several approaches have been tried in the past. Consider adding
these lore links:

"[PATCH 3/4] gpio: dt-bindings: Declare gpio-hog optional for GPIO
subnodes" (2016)
"[PATCH] gpio: 74x164: add lines-initial-states property" (2018)";
"[RFC] Initial state for GPIOs" (2019)

Just so we don't have to constantly look them up for referral.
