PM: sleep: Drop superfluous might_sleep() calls
Drop superfluous might_sleep() calls from dpm_resume(), dpm_complete(),
and dpm_prepare(). These functions already invoke primitives that
implicitly check for sleep in atomic context:
- dpm_resume() and dpm_complete() invoke mutex_lock(), which internally
triggers might_sleep().
- dpm_prepare() calls wait_for_device_probe(), which internally uses
flush_work(), and thus might_sleep().
These annotations are unnecessary and can be dropped to reduce clutter.
