[PATCH] net: phy: add phyid search in vendor specific space

[Florin Chiculita]

There are devices accesible through mdio clause-45, such as
retimers, that do not have PMA or PCS blocks.
This patch adds MDIO_MMD_VEND1 on the list of device addresses
where phyid is searched. Previous order of devices was kept.
