2/2] net: xilinx_emaclite: use readx_poll_timeout() in mdio wait function
On loaded systems with a preemptible kernel the mdio_wait() function may
report an error while everything is working fine:
xemaclite_mdio_wait():
xemaclite_readl() -> chip not ready
--> interrupt here (other work for some time / chip become ready)
if (time_before_eq(end, jiffies))
--> false positive error report
Replace the current code with readx_poll_timeout() which takes care
of the situation.
