3a8ce46ce1 rtc: fsl-ftm-alarm: fix freeze(s2idle) failed to wake 
Use dev_pm_set_wake_irq() instead of flag IRQF_NO_SUSPEND to enable
wakeup system feature for both freeze(s2idle) and mem(deep).

944ed452eb rtc: remove unnecessary error message after platform_get_irq 
The function “platform_get_irq” can log an error already.
Thus omit redundant messages for the exception handling in the
calling functions.

This issue was detected by using the Coccinelle software.

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.

to call ktime_get_real_ts64.
