media: radio: si4713: replace msleep() with usleep_range() for delays less than 20ms
msleep() isn't precise for delays under 20ms and relies on jiffies, which
can lead to sleeps longer than requested, depending on the system's HZ
configurations.
Replace msleep(3) with usleep_range(3000, 4000) to use high-resolution
timers, without forcing the system to wait unnecessarily.
