[LEDE-DEV] [PATCH] imx6: Add ds1307 RTC to kernel for working hctosys

[Petr Štetiar]

Otherwise if we use ds1307 as kernel module, hctosys fails as ds1307 is
being initialized later then hctosys:

 [    2.427349] hctosys: unable to open rtc device (rtc0)
 [    3.714263] snvs_rtc 20cc000.snvs:snvs-rtc-lp: rtc core: registered 20cc000.snvs:snvs-r as rtc1
 [    8.990061] rtc-ds1307 3-006f: rtc core: registered mcp7941x as rtc0
