net: atlantic: Use readx_poll_timeout() for large timeout
Commit
8dcf2ad39fdb2 ("net: atlantic: add hwmon getter for MAC temperature")
implemented a read callback with an udelay(10000U). This fails to
compile on ARM because the delay is >1ms. I doubt that it is needed to
spin for 10ms even if possible on x86.
>From looking at the code, the context appears to be preemptible so using
usleep() should work and avoid busy spinning.
Use readx_poll_timeout() in the poll loop.
