[PATCH v3 3/6] iio: magnetometer: ak8975: replace usleep_range() with fsleep()

[Joshua Crofts <joshua.crofts1@gmail.com>]

Replace usleep_range() calls with fsleep(), passing the minimum value
required by the sensor for hardware delays.

fsleep() automatically selects the optimal sleep mechanism, simplifying
driver code and time management.
