arm64: config: enable RTC_BACKUP_HCTOSYS_DEVICE

without RTC_BACKUP_HCTOSYS_DEVICE=rtc1, hctosys code reads RTCSEC from
tegra-rtc and resetting date to default date (01-01-2013) if date is
set above 2013-year from user.

enable CONFIG_RTC_BACKUP_HCTOSYS_DEVICE and set to rtc1, so that
system reads RTCSEC from pmic-rtc instead of tegra-rtc.
