  1. cpu/fe310: RTC: use rtc_mktime() 

    Use RTC helper functions instead of libc functions.
This gives us y2038 safety by the extended epoch and saves
a good chunk of memory:

picolibc mktime():

   text	   data	    bss	    dec	    hex	filename
  15048	    520	   2504	  18072	   4698	tests/periph_rtc/bin/hifive1/tests_periph_rtc.elf

rtc_mktime():

   text	   data	    bss	    dec	    hex	filename
   7632	     40	   2452	  10124	   278c	tests/periph_rtc/bin/hifive1/tests_periph_rtc.elf
