Subject: [PATCH v1 4/4] usb: dwc3: exynos: Switch from CONFIG_PM_SLEEP guards to pm_sleep_ptr()

Use the new PM macros for the suspend and resume functions to be
automatically dropped by the compiler when CONFIG_PM_SLEEP are disabled,
without having to use #ifdef guards. If CONFIG_PM_SLEEP unused,
they will simply be discarded by the compiler.
