[PATCHv1 4/6] rtc: rtc-isl12057: fix isil vs isl naming for intersil

[Arnaud Ebalard]

When Intersil ISL12057 driver was introduced by commit 70e123373c05
("rtc: Add support for Intersil ISL12057 I2C RTC chip"), the vendor
prefix 'isl' was used instead of the expected 'isil' (Intersil
NASDAQ symbol). Recently, a patch from Philip Zabel (7a6540ca856a,
"ARM: mvebu: Change vendor prefix for Intersil Corporation to isil")
fixed that prefix in ReadyNAS devices .dts files (AFAICT, the only
users).

That patch completes that work to change the remaining values in:

 - Intersil ISL12057 driver (compatible string) and also associated
   Documentation/devicetree/bindings/i2c/trivial-devices.txt file
   to reflect the changes introduced by previous commit from Philip
 - Documentation/devicetree/bindings/vendor-prefixes.txt files to
   avoid future mistakes
