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.
