Subject: [PATCH AUTOSEL 5.15 056/153] arm64: tegra: p2597: Fix gpio for vdd-1v8-dis regulator

From: Diogo Ivo <diogo.ivo@...nico.ulisboa.pt>

[ Upstream commit f34621f31e3be81456c903287f7e4c0609829e29 ]

According to the board schematics the enable pin of this regulator is
connected to gpio line #9 of the first instance of the TCA9539
GPIO expander, so adjust it.
