usb: cdns3: imx: Rework system PM to avoid duplicated operations
The current implementation uses the same callbacks for system PM and
runtime PM suspend/resume without any state checking. This can cause the
clocks to be prepared/unprepared twice, leading to kernel warning issues.
This patch resolves the double prepare/unprepare issues by separating the
runtime PM and system PM handling.
