[PATCH AUTOSEL 6.1 07/26] gpiolib: of: add a quirk for legacy names in MOXA ART RTC

From: Dmitry Torokhov <dmitry.torokhov@gmail.com>

[ Upstream commit eaf1a29665cda1c767cac0d523828892bd77a842 ]

The driver is using non-standard "gpio-rtc-data", "gpio-rtc-sclk", and
"gpio-rtc-reset" names for properties describing its gpios. In
preparation to converting to the standard naming ("rtc-*-gpios") and
switching the driver to gpiod API add a quirk to gpiolib to keep
compatibility with existing DTSes.
