dt-bindings: rtc: isil,isl1208: Document clock and clock-names properties
As per the HW manual, XTOSCB bit setting is as follows
If using an external clock signal, set the XTOSCB bit as 1 to
disable the crystal oscillator.
If using an external crystal, the XTOSCB bit needs to be set at 0
to enable the crystal oscillator.
Document clock and clock-names properties.
