[PATCH AUTOSEL 6.1 06/26] gpiolib: of: add a quirk for reset line for Cirrus CS42L56 codec

[Sasha Levin <sashal@xxxxxxxxxx>]

From: Dmitry Torokhov <dmitry.torokhov@xxxxxxxxx>

[ Upstream commit 944004eb56dc977ad5f882ca4338f45396052317 ]

The controller is using non-standard "cirrus,gpio-nreset" name for its
reset gpio property, whereas gpiod API expects "<name>-gpios".
Add a quirk so that gpiod API will still work on unmodified DTSes.
