All the readl_poll_timeout()s follow the same pattern - test a register
for a bit being clear every 100us, and timeout after 10ms returning
-EBUSY. Wrap this up into a function to avoid duplicating this.

This slightly changes the return value for stmmac_mdio_write() if the
second readl_poll_timeout() fails - rather than returning -ETIMEDOUT
we return -EBUSY matching the stmmac_mdio_read() behaviour.
