bb451661db rtc: fsl-ftm-alarm: avoid struct rtc_time conversions 
Directly call ktime_get_real_seconds instead of converting the result to a
struct rtc_time and then back to a time64_t.

db2a4af115 rtc: fsl-ftm-alarm: switch to ktime_get_real_seconds 
The driver drops the nanoseconds part of the timespec64, there is no need
to call ktime_get_real_ts64.
