[PATCH] staging: greybus: Use fsleep() for delay

[pavankumaryalagada]

From: Yalagada Pavan Kumar <pavankumaryalagada@xxxxxxxxx>

In the loopback function, usleep_range() is used for short delays
and msleep() for longer delays. This requires choosing the delay
function based on the requested time and converting microseconds
to milliseconds when using msleep().

Replace both functions with fsleep(), which selects a suitable
delay method based on the requested time. This avoids the need
to choose the delay function and convert the time manually.
