juhosg bb14a2f07c ar71xx: ag71xx: make switch register access atomic 
Reading of the PHY registers occasionally returns with bogus values
under heavy load. This misleads the PHY driver and thus causes false
link/speed change notifications which leads to performance loss.

This is easily noticable during an iperf session:
