mm/damon/core: Use generic upper bound recommondation for usleep_range()

The upper bound for usleep_range_idle() was taken from the outdated
documentation. As a recommondation for the upper bound of usleep_range()
depends on HZ configuration it is not possible to hard code it.

Use the define "USLEEP_RANGE_UPPER_BOUND" instead.
