rtc: s35390a: Correct RTC alarm behavior to maintain 32KHz output

Browse source 
When setting an RTC alarm, the S35390A_CMD_STATUS2 register will be
set again, which unintentionally disables the 32KHz output, this commit
adds the necessary configuration to set the S35390A_INT2_MODE_32K,
ensuring that the 32KHz output remains enabled at all times.

as a result of this change, the previous commit
7f151d9170 is no longer necessary.
