Hi Tristram
I think it would be better to keep ksz9477_wait_vlan_ctrl_ready(),
ksz9477_wait_alu_ready() etc, and change there implementation to use
readx_poll_timeout(). The function names act as better documentation
for what we are waiting for than the parameters being passed to
readx_poll_timeout().
