rtc: r9701: stop setting a default time
It doesn't make sense to set the RTC to a default value at probe time. Let the core handle invalid date and time. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com> Link: https://lore.kernel.org/r/20201015191135.471249-2-alexandre.belloni@bootlin.com
