rtc: ingenic: Only support probing from devicetree

Browse source 
With the recent work on supporting Device Tree on Ingenic SoCs, no
driver ever probes from platform code anymore, so we can clean a bit
this driver by removing the non-devicetree paths.

If you say yes here you get support for the Ingenic JZ47xx SoCs RTC
controllers.
