Convert the ISL12026 RTC binding from text format to YAML schema.
Remove the legacy text binding.

The new schema enables dtbs_check validation.

-ISL12026 I2C RTC/EEPROM
-
-ISL12026 is an I2C RTC/EEPROM combination device.  The RTC and control
-registers respond at bus address 0x6f, and the EEPROM array responds
-at bus address 0x57.  The canonical "reg" value will be for the RTC portion.
-
-Required properties supported by the device:
-
- - "compatible": must be "isil,isl12026"
- - "reg": I2C bus address of the device (always 0x6f)
-
-Optional properties:
-
- - "isil,pwr-bsw": If present PWR.BSW bit must be set to the specified
-                   value for proper operation.
-
- - "isil,pwr-sbib": If present PWR.SBIB bit must be set to the specified
-                    value for proper operation.
-
-
-Example:
-
-	rtc@6f {
-		compatible = "isil,isl12026";
-		reg = <0x6f>;
-		isil,pwr-bsw = <0>;
-		isil,pwr-sbib = <1>;
-	}

Duplicate signature. Please run scripts/checkpatch.pl on the patches and
fix reported warnings. After that, run also 'scripts/checkpatch.pl
--strict' on the patches and (probably) fix more warnings. Some warnings
can be ignored, especially from --strict run, but the code here looks
like it needs a fix. Feel free to get in touch if the warning is not
clear.

Rest is fine and duplicated SoB might be just ignored due to cut
separator.
