RTC: Skip rtc_init() in S3 resume path

In addition to not clearing the pending interrupts, we also
    don't want to reset the RTC control register when booting
    with an S3 resume.

On most new systems, when the RTC well is losing power, we
    will also lose state that is required to perform a resume,
    so we end up in a normal boot anyways. Hence don't do any
    RTC initialization in the S3 resume path.
