[PATCH v2] staging: media: atomisp: use usleep_range instead of msleep for short delays

[Ramon Watson Vilar]

The msleep() function is not precise for delays shorter than 20ms and
can sleep for significantly longer than requested. Replacing it with
usleep_range() improves accuracy and is the recommended practice
according to documentation.
