Philippe De Muyter 4d61ff6b99 rtc: add rtc-abx80x, a driver for the Abracon AB x80x i2c rtc
This is a basic driver for the ultra-low-power Abracon AB x80x series of RTC
chips. It supports in particular, the supersets AB0805 and AB1805.
It allows reading and writing the time, and enables the supercapacitor/
battery charger.
