ACPI: TAD: Split acpi_tad_rtc_read_time() 



Move the code converting a struct acpi_tad_rt into a struct rtc_time
from acpi_tad_rtc_read_time() into a new function, acpi_tad_rt_to_tm(),
to facilitate adding alarm support to the driver's RTC class device
interface going forward.

No intentional functional impact.
