Subject: [PATCH AUTOSEL 6.5 17/34] gpiolib: of: Add quirk for mt2701-cs42448 ASoC sound

From: Linus Walleij <linus.walleij@...aro.org>

[ Upstream commit 9e189e80dcb68528dea9e061d9704993f98cb84f ]

These gpio names are due to old DT bindings not following the
"-gpio"/"-gpios" conventions. Handle it using a quirk so the
driver can just look up the GPIOs.
