Convert the abracon abx80x rtc text bindings to dt-schema format.

Additionally added "interrupts" property which was missing from text
format, because abx80x and driver support them.

-Abracon ABX80X I2C ultra low power RTC/Alarm chip
-
-The Abracon ABX80X family consist of the ab0801, ab0803, ab0804, ab0805, ab1801,
-ab1803, ab1804 and ab1805. The ab0805 is the superset of ab080x and the ab1805
-is the superset of ab180x.
-
-Required properties:
-
- - "compatible": should one of:
-        "abracon,abx80x"
-        "abracon,ab0801"
-        "abracon,ab0803"
-        "abracon,ab0804"
-        "abracon,ab0805"
-        "abracon,ab1801"
-        "abracon,ab1803"
-        "abracon,ab1804"
-        "abracon,ab1805"
-        "microcrystal,rv1805"
-	Using "abracon,abx80x" will enable chip autodetection.
- - "reg": I2C bus address of the device
-
-Optional properties:
-
-The abx804 and abx805 have a trickle charger that is able to charge the
-connected battery or supercap. Both the following properties have to be defined
-and valid to enable charging:
-
- - "abracon,tc-diode": should be "standard" (0.6V) or "schottky" (0.3V)
- - "abracon,tc-resistor": should be <0>, <3>, <6> or <11>. 0 disables the output
-                          resistor, the other values are in kOhm.
