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.
