[PATCH 3/4] rts5208: Fix usleep_range is preferred over udelay

[Lukas Schneider]

This patch fixes the issue reported by checkpatch:

CHECK: usleep_range is preferred over udelay;
see Documentation/timers/timers-howto.txt

It's save to sleep here instead of using busy waiting,
because we are not in an atomic context.
