bad385ab7c cpu/efm32: RTC Series 0: use RTC helper functions 
By using the RTC helper functions instead of POSIX mktime()/gmtime()
we can not only extend the RTC range beyond Y2038.

For tests/periph_rtc:

before:

   text	   data	    bss	    dec	    hex	filename
  28028	    248	   2472	  30748	   781c stk3700/tests_periph_rtc.elf

after:

   text	   data	    bss	    dec	    hex	filename
  19400	    144	   2424	  21968	   55d0 stk3700/tests_periph_rtc.elf
