Subject: rtc: ds1307: remove member nvram_offset from struct ds1307

Git-commit: 969fa07b9479f435bc4363e4ff75db99fc9b24fb
Patch-mainline: v4.14-rc1
References: fate#326530,fate#326531,fate#326535,fate#326538,fate#326539

Remove member nvram_offset from struct ds1307 and use the value stored
in struct chip_desc directly.
