rtc:ds3232/ds3231: Add support to generate 32KHz output
RTC devices can generate 32KHz output if for -DS3232 device, EN32KHz bit and BB32KHz bit are set -DS3231 device, EN32KHz bit is set, BB32KHz bit is don't care Patch adds rtc_enable_32khz_output() which when called will enable 32KHz output on 32KHz pin Signed-off-by: Priyanka Jain <Priyanka.Jain@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>
