lan743x: Remove phy_read from link status change function

Browse Source 
[ Upstream commit a0071840d2 ]

It has been noticed that some phys do not have the registers
required by the previous implementation.

To fix this, instead of using phy_read, the required information
is extracted from the phy_device structure.
