rtc: ds1307: add frequency_test_enable attribute on m41txx
On m41txx you can enable open-drain OUT pin to check if offset is ok.
Enabling OUT pin with frequency_test_enable attribute, OUT pin will tick
512 times faster than 1s tick base.
Enable or Disable FT bit on CONTROL register if freq_test is 1 or 0.
