rtc: ds1307: remove legacy check for "isil, irq2-can-wakeup-machine" property

Browse source 
Commit 8b44f5be20 ("ARM: dts: armada: replace isil,irq2-can-wakeup-machine with wakeup-source property")
removed the last usage of "isil,irq2-can-wakeup-machine" almost
two years ago. So I think we can get rid of supporting this
legacy binding.
